High-power RF MLC capacitors deliver high frequency performance

10 September 2002 Passive Components

The Hi-Q Series of MLC capacitors from AVX offers superior electrical characteristics for various high-frequency applications. For use in high-power RF applications, these products feature ultra-low equivalent series resistance (ESR) and superior high current handling capability in small case sizes. These high voltage, surface-mount capacitors also offer exceptional heat dissipation characteristics and high-frequency performance. The typical Q (quality factor) for this family is 10 000 minimum, making it ideal for high current applications. (Q is the inverse of the dissipation factor; Q = 1/DF).

Typical high power and high voltage levels are for applications in RF power amplifiers, inductive heating, high magnetic field environments (MRI coils), medical and industrial electronics.

The Hi-Q Series capacitors are available in case sizes 2325 and 3739, and feature capacitance values from 10 000 pF down to 10 pF with tolerances to ±1%. Rated voltage ranges from 300 to 4000 V d.c., with a temperature coefficient of 90±30 ppm/°C over the temperature range from -55 to 125°C.
