Iselin, N.J. EPCOS has launched a new series of polymer capacitors that can operate at ambient temperatures up to 125°C with a standard voltage derating (66% of rated voltage).
The B4529W series follows the trend toward increased modularization in on-board
switchmode power supplies for applications in industrial electronics, networks and
telecom systems where large-scale integration of active and passive components in a
minimum of space can result in temperatures above 100°C.
The new polymer types are currently available in D and E cases sizes with a V case size to be added later. Capacitance values range from 100 to 680 microfarads (μF) for rated voltages from 2.5 to 10 V. Equivalent series resistance (ESR) is less than 35 microwatts (μW). The polymer series is free of hazardous substances as defined by the RoHS directive, said the company.
Part #B45296W2227M529 is priced at $0.70 each in large volumes.
