Wet Tantalum Capacitors-High Energy EP1

Part Number Information
Part #: Price/Availability:
TANEP1A203K035CZSSA Browse Inventory

Built on Vishay’s proven SuperTan® technology, the EP1 features an ultra high capacitance range from 2,000 µF to 30,000 µF and voltage ratings from 25 VDC to 125 VDC in the A case code. 


The EP1’s industry-leading values include a capacitance of 13,000 µF at 50 V in the A case size, which is 18 % greater than the closest competing device. The capacitor features a standard capacitance tolerance of 20 %, with 10 % tolerance available. Optimized for pulse power and energy hold-up applications in laser guidance, radar, and avionics systems, the EP1 is housed in an all-tantalum, hermetically sealed case for increased reliability. The device operates over a temperature range of -55 °C to +85 °C, to +125 °C with voltage derating, and provides maximum ESR down to 0.030 Ω at 1 kHz and +25 °C. The capacitor is available with tin/lead (Sn/Pb) and RoHS-compliant 100 % tin terminations.
