Microwave MLCCs

27 April 2011 Passive Components

AVX has developed a multilayer capacitor (MLC) chip series with new dielectric and internal electrode materials in a 0402 size. These materials allow for very low equivalent series resistance and high series resonance. Designated the UQCL series, the chips are suitable for RF/microwave applications ranging from 10 MHz to 4,2 GHz.

The new series has a fine grained, high density, high purity dielectric material to keep out moisture, and includes an electrode system that has been optimised for high-frequency performance. This makes the parts ideal for applications with high current carrying capabilities and high quality factors. Applications such as microwave RF/IF amplifiers, mixers, oscillators, low noise amplifiers and filter networks, as well as medical devices such as MRI coils, can benefit from the UQCL series’ characteristics.

Available with voltages up to 200 V d.c., the chips offer high stability under the stresses of changing voltage, frequency, time and temperature.
