Polymer tantalum chip capacitors operate in harsh environments

Polymer tantalum chip capacitors operate in harsh environmentsVishay Intertechnology, Inc. has launched a new series of vPolyTan surface-mount polymer tantalum chip Capacitors that is designed to operate in high temperature, high humidity operating conditions. The Vishay Polytech T50 series capacitors also feature a robust design with improved hermeticity for increased protection in harsh environments.

The devices offer an operating temperature range from -55°C to 125°C and withstand temperature humidity bias (THB) testing of 85°C, 85 % relative humidity for 500 hours. These specifications make the capacitors suited for decoupling, smoothing, and filtering in the harsh industrial, military, aerospace, and edge computing applications, said Vishay.

Offered in the D case (EIA 7343-30) size, the surface-mount polymer tantalum molded chip capacitors feature ultra-low equivalent series resistance (ESR) down to 25 mΩ and ripple current to 3.0 A. Capacitance values range from 10 µF to 330 µF over Voltage ratings from 2.5 V to 35 V with a capacitance tolerance of ±2 %. The capacitors are Rohs-compliant, halogen-free, and Vishay Green. The series has a Moisture Sensitivity Level 3.
