Polymer Capacitor Operates to 125°C

A new polymer chip capacitor has been designed to operate at ambient temperatures up to 125°C and derating to 66% of rated voltage. The B4529W capacitor is currently available in case sizes D or E with capacitances from 100 to 680 µF for rated voltages from 2.5V to 10V. Equivalent series resistance is less than 35 μΩ. The polymer series is free of hazardous substances as defined by the RoHS directive. Pricing for the B45296W-2227M529 is $0.70 each in large quantities. EPCOS INC., Iselin, NJ. (800) 888-7729.
