TDK recommends a soldering temperature profile with a peak temperature of 260°C for 10-30 seconds, and a maximum of 3 reflows. However, it's always best to consult the specific soldering guidelines provided by TDK or to consult with their technical support team for more detailed information.
TDK provides a reliability test report that outlines the capacitor's performance over time, including changes in capacitance and ESR. According to the report, the B57421V2222J062 capacitor is expected to retain at least 85% of its initial capacitance and ESR after 1,000 hours of operation at 85°C and 85% relative humidity.
TDK recommends a voltage derating of 10% for the B57421V2222J062 capacitor. This means that the capacitor should not be operated above 90% of its rated voltage (22V) to ensure reliable performance and prevent premature failure. Voltage derating can affect the capacitor's performance by reducing its capacitance and increasing its ESR.
The B57421V2222J062 capacitor is suitable for high-frequency applications up to 100 kHz. However, its performance may degrade at higher frequencies due to increased ESR and ESL. TDK provides a frequency characteristics graph in the datasheet that shows the capacitor's impedance and ESR vs. frequency. Engineers should consult this graph to determine the capacitor's suitability for their specific high-frequency application.
TDK recommends storing the B57421V2222J062 capacitor in its original packaging or in a similar package that protects it from mechanical stress, moisture, and electrostatic discharge. The capacitor should be stored in a dry, cool place, away from direct sunlight and heat sources. Engineers should also follow proper handling and soldering procedures to prevent damage during assembly.
