Polymer capacitors offer extended life under stress

June 08, 2015 // By Graham Prophet
Panasonic Automotive & Industrial Systems’ POSCAP TC series polymer capacitors withstand high temperatures range, have a low ESR and a high resistance to stress suiting them to industrial and other applications that require a life of 10 years.

The wide operating temperature range of -55 to +125C ensures that devices last for 10 years at 85C and a ripple current rating of 6.1 Arms enables them to survive in high stress environments.

POSCAP TC series devices also feature a low ESR down to 5 mΩ, a capacitance range of 100-1000 µF and are rated for voltages from 2 to 10V. Panasonic adds that, compared to other capacitor technologies, they are more stable over temperature and frequency. They are non-flammable and have an inherent self-healing mechanism, so reliability is increased. And because no derating is required, BOM count can be minimised.
