vPolyTan Polymer Surface-Mount Chip Capacitors with Ultra low ESR Bring Reliable Performance to Harsh Operating Conditions

Vishay Intertechnology has introduced a new series of vPolyTan surface-mount polymer tantalum molded chip capacitors that feature a robust design with improved hermeticity for increased protection in harsh environments. The new T50 series capacitors are designed to deliver reliable performance in high humidity operating conditions and are ideal for decoupling, smoothing, and filtering in the environments of industrial, military, aerospace, and edge computing applications. These devices offer high-temperature operation to +125 °C and withstand temperature humidity bias (THB) testing of 85°C, 85% relative humidity for 500 hours.

The T50 Series offers a wide capacitance range from 10 µF to 330 µF overvoltage ratings from 2.5 V to 35 V, and a capacitance tolerance of ± 20 %. Offered in the D case (EIA 7343-30) size, these devices feature ultra-low ESR down to 25 mW and ripple current to 3.0 A.

Features

• Operating temperature range of -55°C to +125°C

• High temperature and high humidity operation

• Qualification testing based on AEC-Q200 with 85°C / 85% RH performance testing up to 500 hours

Applications

• Decoupling, smoothing, filtering

• Switch mode and point of load power supply

• Automotive - infotainment and cockpit electronics

Availability

Samples and production quantities of the T50 series are now available with lead times of 12 to 14 weeks and pricing for U.S. delivery starts at $0.45 per piece.
