AVX adds low-noise MLCC to product offering
AVX has expanded its multilayer ceramic capacitor (MLCC) range to include the QM series low-noise high-capacitance version for audio frequency applications.
The QM series is said to reduce noise characteristics while providing high capacitance with low working voltage, making it suitable for mobile phone, hard disk drive, and LCD panel driver circuit applications.

In addition, the QM series is well suited for use as a low pass filter for audio amplifier output or as a coupling capacitor.
Kazushige Takamori, product manager at AVX, said: 'Polarisation causes high dielectric ceramic to have a piezo-electric response.
'This piezo effect can be passed to the PCB and cause board running.
'Conversely vibrations from the PCB can induce very low spurious voltages across the capacitor.
'Standard MLCC construction has multilayer electrode direction horizontal to the PCB, which can allow mechanical resonance from the PCB to induce audio frequency noise.
'The QM series inherently reduces low-frequency audio noise,' Takamori added.
The lead-free, RoHS-compliant QM series is available in Class II X5R dielectric and case sizes from 0603 to 0805 with voltage ratings ranging from 4V to 16V.
The X5R version features a high CV rating, an operating temperature range of -55C to +85C and a capacitance variation is within +/-15 per cent.
