Rugged capacitors resist vibration and operate to 135C

DMTL has made available engineering kits which will introduce designers to the features of Suncon's EP-Cap polymer hybrid electrolytic capacitors.

Designed to suit a wide range of commercial and high reliability applications including automotive, power supplies and metering systems, the EP-Cap is a polymer aluminium electrolytic capacitor with a hybrid cathode formed by combining an electrolyte and electro-conductive polymer with high conductivity. EP-Cap capacitors feature rated voltages up to 125V and performance and reliability levels are maintained at temperatures up to 135ºC.

The capacitors feature a very low ESR at high frequencies when compared with conventional electrolytics while the structure of the hybrid cathode electrolyte allows EP-cap devices to have the same self-healing properties as traditional aluminium electrolytic capacitors. EP-Cap devices are highly stable when exposed to temperature fluctuations and the range include models with operating temperatures ranging from -55 to +135ºC and load life ratings to 2000 hours. Voltage options are from 6.3 to 125 VDC with capacitance values from 10 to 1000 µF. The EP-Cap capacitors measure from 6.3mm diameter x 7.7mm long to 10mm x 12.5mm.
