A passive components manufacturer has developed a multilayer capacitor (MLC) chip that uses a dielectric and internal electrode materials that allow for a
significantly lower equivalent series resistance than previous versions. Designated the UQ Series by developer AVX Corp, the chips are well suited 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,” says Larry Eisenberger, AVX product manager. “This makes the UQ Series ideal for applications with high current carrying capabilities. The capacitors also offer Ultra low ESR and 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.
