New MLCC series features near-pure silver electrodes for high conductivity

AVX has introduced a new series of microwave MLCCs with near-pure silver (Ag) electrodes, which both enhance performance and reduce costs. Providing higher conductivity than competing non-precious metal RF capacitors, the new UQ Series MLCCs feature ultra-low ESR, high Q, high self-resonance, and a capacitance range spanning 0.1pF to 1000pF. Applications for the UQ Series include RF power amplifiers, low noise amplifiers, filter networks, and MRI systems.

“By utilizing near-pure silver electrodes on the new UQ Series capacitors, we have been able to provide higher conductivity than competitive non-precious metal technologies while remaining highly competitive in terms of cost,” said Larry Eisenberger, Product Manager at AVX.

Lead-free and RoHS compliant, the 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%. Priced to be competitive 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.

The 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.
