CDE Power Conversion Type PC Series capacitors deliver a full 60,000 hour life at rated voltage, at a hot-spot temperature (area reaching the highest temperature) of 85°C. Type PC capacitors are wound using a high crystalline metallized polypropylene (HCPP) film, which possesses an extremely low dissipation factor. Click here to read technical paper
Based on your specified operating conditions of voltage, ripple current, heatsink characteristics, airflow and ambient temperature, this model calculates the internal hotspot temperature and expected lifetime, reliability and failure rate.

While steady-state analysis of aluminum electrolytic capacitors is straightforward, predicting transient electrical and thermal response is much more involved. In this presentation the modeling of transient electrical, thermal and lifetime behavior of aluminum electrolytic capacitors is discussed, focusing on large (> 0.1 liter) DC link capacitors.
