MLC has dielectric/internal electrode materials
AVX
UQ series MLC components
AVX has developed a multilayer capacitor (MLC) chip that utilises dielectric and internal electrode materials, said to give lower equivalent series resistance than previous versions.
Designated the UQ series, the components are suitable for RF/microwave applications ranging from 10MHz to 4.2GHz.
'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.' He added: '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 500V DC, the UQ Series offers stability under the stresses of changing voltage, frequency, time and temperature.
