1210, 1825, 2225, 3640 X7R Dielectric, High Voltage MLC
Chips, Capacitor
General Description:
High value, low leakage and small size are difficult parameters
to obtainin capacitors for high voltage systems. AVX special
high voltage MLC chip 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 MLC chip products. Special precautions
must be taken in applying these chips in surface mount
assemblies. The temperature gradient during heating or cooling cycles should not exceed 4ºC per second.
The preheat temperature must be within 50ºC of the peak temperature reached by the ceramic bodies
through the soldering process. Chip sizes 1210 and larger should be reflow soldered only. Capacitors may
require protective surface coating to prevent external arcing. For 1825, 2225 and 3640 sizes, AVX offers
leaded version in either thru-hole or SMT configurations (for details see section on high voltage leaded MLC
chips).
