Polymer tantalum chip capacitors operate despite humidity

Suitable for harsh operating conditions, the T50 series of polymer tantalum moulded chip capacitors operate at temperatures up to +125 degrees C, says Vishay Polytech. They are also able to withstand temperature humidity bias (THB) testing of 85 degrees C / 85 per cent RH for 500 hours.

The series of vPolyTan surface mount polymer tantalum moulded chip capacitors have a robust design with improved hermeticity for increased protection in harsh environments. The temperature and temperature humidity characteristics make the capacitors suitable for decoupling, smoothing, and filtering in the harsh environments of industrial, military, aerospace, and edge computing applications. 

The T50 capacitors are offered in the D case (EIA 7343-30) size. Models in the series feature low ESR down to 25 mOhm and ripple current to 3A. They also offer a wide capacitance range from 10 to 330 microF over-voltage ratings from 2.5 to 35V and a capacitance tolerance of ± 20 per cent. 

The capacitors are RoHS-compliant and halogen-free. Samples and production quantities of the T50 series are available now, with lead times of 12 to 14 weeks. 

Vishay claims to manufacture one of the world’s largest portfolios of discrete semiconductors and passive electronic components for the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
