What is reliability assurance for COTS capacitors?
Reliability Assurance for COTS Capacitors To be presented by Alexander Teverovsky at the NEPP Electronics Technology Workshop (ETW), Greenbelt, MD, June 13-16, 2022. Burn-in (BI) and life testing (LT) are the most important reliability related elements of quality assurance for components used in space systems.
What are the coefficients of sample-to-sample variation in a capacitor?
The coefficients of sample-to-sample variations within one lot are typically in the range from 5 to 50%, and the values of I10 for different lots of capacitors might vary from 0.01 A to more than 10 A. Variations of Q are smaller than I10 and are relatively independent on the value of limiting currents.
What is a fixed electric double-layer capacitor?
Fixed electric double-layer capacitors for use in electric and electronic equipment - Part 1: Generic specification IEC 62391-1:2022 applies to fixed electric double-layer capacitors (hereafter referred to as capacitors) mainly used in DC circuits of electric and electronic equipment.
What is the temperature range of a polymer capacitor?
polymer capacitors. Variations of I10 with temperature in the range from -55 °C to +125 °C for different types of capacitors are shown in Fig.9. To avoid reduction of currents caused by repeat measurements, different groups of capacitors (3 to 5 samples in a group) were used for the testing at each temperature.
What is PST & ACC test for polymer tantalum capacitors?
For this reason, PST in addition to the surge current testing, is recommended as a screening and lot acceptance procedure for polymer tantalum capacitors for space applications. The level of ACC can be evaluated by currents measured at 10 msec, I10, or energy dissipated in the process of current relaxation during PST, Q.
What is the level of review for polymer tantalum capacitors?
Level of Review: This material has been technically reviewed by technical management. Due to dry environments, anomalous charging currents (ACC) in polymer tantalum capacitors (PTC) could cause malfunctions or failures in space systems. Currently, there is no standard metric to assess this effect, and factors affecting ACC are not well understood.
