The component under review is a surface mount device, with a package size of 0402 (1005 metric), and a voltage rating of 25V. The data provided presents LCR measurements obtained at both 1 Volt and 10 Volts across varying test frequencies.

Pros:

As we dive into the capacitance, series resistance, dissipation factor, and quality factor sections, we will explore each aspect in detail and draw conclusions based on the comparative analysis with the benchmark data. This review aims to provide engineers with valuable information to help them assess the suitability of this capacitor for use in their circuits.

Impedance

The CGA2B3X7R1E104K050BB ceramic capacitor exhibits a satisfactory impedance profile across various tested frequencies when concerning the statistical benchmark. At one of the lower testing frequencies, specifically 10 kHz, the capacitor demonstrates an impedance of 156.6k ohms compared to the benchmark average of 157.2k ohms. This comparison highlights that the CGA2B3X7R1E104K050BB's performance closely aligns with the expected performance within this frequency range, reflecting its efficient behavior.

Similarly, at higher frequencies such as 100 kHz, the CGA2B3X7R1E104K050BB exhibits an impedance of 17.58k ohms compared to the average benchmark impedance of 18.07k ohms. This illustrates the component's consistency and reliability in its performance at increased frequencies, indicating its versatile functionality.

When operated at a higher voltage level of 10 volts, the component continues to keep pace with or surpass the average benchmark impedance values. For instance, at 50 kHz, the CGA2B3X7R1E104K050BB measures an impedance of 29.66k ohms, which exceeds the average 34.91k ohms benchmark impedance while remaining within the specified tolerance ranges. This demonstrates the capacitor's ability to maintain consistent performance under varying voltage conditions.

However, it is essential to note that impedance measurements at the highest test frequencies, specifically in the 750 kHz to 1MHz range, were not provided at 10 volts. Taking this limitation into account, engineers should exercise diligence when incorporating the CGA2B3X7R1E104K050BB capacitor in their designs, particularly in scenarios where higher frequencies and voltages are necessary for optimal performance. Careful evaluation of the component's applicability in such conditions is crucial to ensure reliable operation and overall design effectiveness.

Capacitance

In the low test frequency range (5 - 1k Hz), the CGA2B3X7R1E104K050BB capacitor demonstrates superior performance compared to the average series capacitance of the statistical benchmark at both 1 Volt and 10 Volts. For instance, at 1 kHz and 1 Volt, the component measures 99.09 nF, in comparison to the benchmark's average of 99.04 nF. This positive performance trend can be observed until 10 kHz at 1 Volt and 1 kHz at 10 Volts, where the component's measurements begin to slightly underperform relative to the benchmark averages.

As the test frequency increases to the higher range (10k - 1M Hz), the performance of CGA2B3X7R1E104K050BB capacitor becomes less consistent when compared to the statistical benchmark averages. It exhibits a below-average performance in this frequency range. For example, at 50 kHz and 1 Volt, the component measures 92.55 nF, which lags behind the benchmark average of 91.32 nF. The underperformance becomes even more evident at 50 kHz and 10 Volts, where the component measurement reaches 107.3 nF, as opposed to the benchmark average of 91.32 nF.

Due to the performance limitations of the CGA2B3X7R1E104K050BB capacitor at higher test frequencies, engineers and designers must take into account their application requirements carefully when selecting this component. Alternative capacitors possessing more favorable performance characteristics at higher frequencies might be more suitable, depending on the specific use case and system requirements.

Series Resistance

The CGA2B3X7R1E104K050BB capacitor from TDK Corporation demonstrates a varied performance when compared with the statistical benchmark values for capacitors in the Ceramic: X7R category. This assessment is based on test results obtained under 1 Volt test conditions, wherein the component exhibits moderate series resistance values ranging from 5 Hz to 100 kHz, followed by progressively higher resistance in the frequency range of 150 kHz to 1 MHz. By contrasting this component's resistive values, we can identify its limitations as well as advantages that can help engineers in determining its suitability for their circuits.

In comparison to the average resistance demonstrated by other similar components, the CGA2B3X7R1E104K050BB presents relatively higher resistance values, particularly within the frequency range of 20 kHz to 1 MHz. For instance, at 20 kHz and 1V, the capacitor's resistance of 1.853 Ohms is approximately 70% higher than the statistical benchmark average of 1.039 Ohms. A similar situation is observed at 100 kHz, where the component exhibits a resistance of 491 mOhms. This value is 80% higher than the average benchmark of 271.2 mOhms.

However, the CGA2B3X7R1E104K050BB outperforms the statistical benchmark under several test conditions. The component manages to exhibit lower resistance values at 10 Hz and 50 Hz. Specifically, at 10 Hz, its resistance of 3.757k Ohms is found to be 13% lower than the average resistance of 4.329k Ohms offered by its counterparts. Additionally, at 50 Hz, the capacitor yields a resistance of 717.1 Ohms, amounting to 17% lower than the benchmark's average of 865 Ohms.

When subjected to 10 Volt test conditions, it becomes apparent that the series resistance performance of the CGA2B3X7R1E104K050BB capacitor remains characteristically higher than the statistical benchmark values across most of the test frequencies. Although the component offers considerably lower resistance values at 5 Hz, 10 Hz, and 50 Hz, its resistance increases between 75 kHz and 700 kHz, making it less optimal for circuits that require lower resistance values. In summary, the series resistance performance of the CGA2B3X7R1E104K050BB capacitor does not consistently align with the Ceramic: X7R statistical benchmark data, potentially limiting its applicability in specific engineering applications that demand tighter adherence to benchmarks.

Dissipation Factor and Quality Factor

In our evaluation of the TDK Corporation CGA2B3X7R1E104K050BB capacitor, we analyzed the Dissipation Factor (Df) and Quality Factor (Q) as two key indicators of performance. The Dissipation Factor is a measure of how effectively a capacitor dissipates energy, represented by the ratio of the resistive power loss to the reactive power. A lower Df is preferable, indicating less energy dissipation and hence better performance under the given circumstances.

Our assessment of the capacitor's Df was conducted across a wide range of frequencies at both 1 V and 10 V. We observed that the component demonstrated relatively good performance at 1 V, with Df values remaining within the range of 0.014 to 0.025. However, upon increasing the voltage to 10 V, we noticed a degradation in its Df performance, as values shifted towards the range of 0.025 to 0.046. This implies that at higher voltages, the energy dissipation characteristics of this capacitor may deteriorate.

The Quality Factor, on the other hand, is a measure of a component's performance and is inversely proportional to the energy dissipation (Df). A higher Q value is desirable, indicating better performance. In our study, we found that the capacitor achieved a Q ranging from 40.27 to 72.21 at a voltage of 1 V. However, an increase in the applied voltage to 10 V caused the capacitor's Q factor to decrease, falling within the range of 19.65 to 40.95. This observation confirms the trend established by the Dissipation Factor: the Quality Factor for the TDK Corporation CGA2B3X7R1E104K050BB capacitor also diminishes at higher voltages, suggesting a decline in its performance under those conditions.

When evaluating the performance of this capacitor, it is important to consider its consistent capacitance values, impedance, series resistance, dissipation factor, and quality factor when compared to the statistical benchmark data at 1 Volt and 10 Volts.

At the lower frequencies (5 Hz to 100 kHz), this capacitor demonstrates similar average values with minor deviations from the impedance benchmark data and maintains a relatively stable dissipation factor range. However, it starts to outperform the statistical benchmark data from around 50 kHz, especially in terms of impedance and dissipation factor, showing superior performance in these aspects.

The capacitors series resistance and quality factor closely follow the benchmarks across all test frequencies, indicating acceptable standards for these parameters.
