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 B72220T2151K105 capacitor exhibits a capacitance change of ±15% and an ESR change of ±30% after 1,000 hours of operation at 85°C and 85% RH. However, it's essential to consult the specific report for this capacitor or to contact TDK's technical support team for more information.
The B72220T2151K105 capacitor has an MSL rating of 2a, which means it can withstand a maximum of 30°C and 60% RH for 24 hours before soldering. This rating indicates that the capacitor is relatively resistant to moisture and can be handled in a typical production environment.
The B72220T2151K105 capacitor is designed to meet the requirements of IEC 60384-16 for vibration resistance. However, it's essential to consult TDK's vibration test report and to perform additional testing to ensure the capacitor meets the specific requirements of your application. You may also need to consider additional mechanical fixation or potting to ensure the capacitor's reliability in high-vibration environments.
While the datasheet provides ESR values at 100 Hz, TDK can provide additional information on the capacitor's ESR at higher frequencies upon request. Typically, the ESR of the B72220T2151K105 capacitor will increase at higher frequencies due to the inductive effects of the internal electrodes and leads. You can contact TDK's technical support team for more information on the capacitor's high-frequency ESR characteristics.
