Microwave MLCCs

12 June 2013 Passive Components

AVX has introduced a new series of microwave MLCCs (multi-layer ceramic capacitors) with near-pure silver (Ag) electrodes, which both enhance performance and mitigate cost.

Exhibiting higher conductivity than competing non-precious metal RF capacitors, the UQ series features ultra-low ESR, high Q, high self-resonance and a capacitance range spanning 0,1 pF to 1000 pF. Ideal applications include RF power amplifiers, low-noise amplifiers, filter networks and MRI systems.

Lead-free and RoHS compliant, the capacitors are available in seven voltages, ranging from 50 to 500 V, and in eight capacitance tolerances, ranging from ±0,1 pf to ±20%. Competitively priced with other non-precious metal RF capacitors, the series is available in six case sizes: 0605, 1210, 0709, 0402, 0603 and 0805, and with three termination styles: nickel barrier Sn/Pb (60/40), 100% tin and non-magnetic barrier/tin.

The UQ series is rated for use in temperatures ranging from -55°C to +125°C. It also meets or exceeds the requirements of EIA-198, MIL-PRF-55681 and MIL-PRF-123.
