High-frequency capacitors cut stray inductance

Medium-power devices are targeted at situations where standard capacitors cannot handle the high-frequency ripple currents experienced.

Available now from AVX, the FFVS range of medium-power capacitors combine very high frequency operation with the lowest stray inductance of any product on the market.

Suitable for applications such as very high frequency ripple (above 100kHz) DC filtering for induction heating, the devices exhibit an inductance of less than 10nH on certain models.

600V capacitors are offered in capacitance values of 22, 90, 140 and 195uF; 800V devices are rated at 58, 92 and 128uF; and 900V models at 34, 40, 65 and 90uF.

Featuring a dry polypropylene dielectric technology, FFVS capacitors are very reliable with an extended life.

According to Gilles Terzuli, AVX's Power Film Marketing Manager: "Our new FFVS series capacitors are suitable for situations where standard devices are not able to handle the high frequency ripple currents experienced".

Typical applications include medical power supplies used in X-ray and MRI equipment.
