High Voltage Chips

For 500V to 5000V Applications

High value, low leakage and small size are difficult parameters to obtain

in capacitors for high voltage systems. AVX special high voltage MLC

chips capacitors meet these performance characteristics and are

designed for applications such as snubbers in high frequency power

converters, resonators in SMPS, and high voltage coupling/DC blocking.

These high voltage chip designs exhibit low ESRs at high frequencies.

Larger physical sizes than normally encountered chips are used to

make high voltage chips. These larger sizes require that special pre-

cautions be taken in applying these chips in surface mount assem-

blies. This is due to differences in the coefficient of thermal expansion

(CTE) between the substrate materials and chip capacitors. Apply heat

at less than 4°C per second during the preheat. Maximum preheat

temperature must be within 50°C of the soldering temperature.

The solder temperature should not exceed 230°C. Chips 1808 and

larger to use reflow soldering only.

Capacitors with X7R Dielectrics are not intended for AC line filtering

applications.

Contact plant for recommendations. Capacitors may require protective

surface coating to prevent external arcing.
