Multilayer ceramic capacitors have near-pure silver electrodes for high conductivity

March 12, 2013 // By Julien Happich
AVX has introduced a series of microwave MLCCs 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 MLCCs feature ultra-low ESR, high Q, high self-resonance, and a capacitance range spanning 0.1pF to 1000pF. Ideal applications for the UQ Series include RF power amplifiers, low noise amplifiers, filter networks, and MRI systems. Lead-free and RoHS compliant, AVX's high-performance UQ Series MLC RF capacitors are available in seven voltages, ranging from 50-500V, and in eight capacitance tolerances, ranging from ±0.1pf to ±20%. Competitively priced with other non-precious metal RF capacitors, the series is also 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. Teh UQ Series is rated for use in temperatures ranging from -55°C to +125°C. The series also either meets or exceeds the requirements of EIA-198, MIL-PRF-55681, and MIL-PRF-123.
