AVX Corporation has developed a multilayer capacitor (MLC) chip that utilises new dielectric and internal electrode materials, which allow for a significantly lower equivalent series resistance than previous versions. Designated the UQ series, these components are ideal for RF/microwave applications ranging from 10 MHz to 4.2 GHz.

“The new design has a fine-grained, high density, high purity dielectric material to keep out moisture, and includes precious metal electrodes,” said Larry Eisenberger, AVX product manager. “This makes the UQ series ideal for applications with high current carrying capabilities and high quality factors. The capacitors also offer Ultra low ESR and very high series resonance.”

Applications such as microwave RF/IF amplifiers, mixers, oscillators, low noise amplifiers, and filter networks, as well as medical devices such as MRI coils, would all benefit from the UQ Series’ characteristics, according to Eisenberger.

Available in 1210, 0605 and 0709 sizes with voltages up to 500 VDC, the UQ Series offers superior stability under the stresses of changing voltage, frequency, time and temperature.
