Microwave MLCCs that operate in full military temperature range introduced by AVX

GREENVILLE, S.C., 12 March 2013. AVX Corp. in Greenville, S.C., is introducing the UQ series of microwave multi-layer ceramic capacitors (MLCCs) that operate in the full military temperature range for RF power amplifiers, low noise amplifiers, filter networks, and MRI systems.

The microwave capacitors have near-pure silver (Ag) electrodes, which enhance performance and mitigate cost, company officials say. Exhibiting higher conductivity than competing non-precious metal RF capacitors, AVX's UQ series MLCCs have ultra-low ESR, high Q, high self-resonance, and a capacitance range spanning 0.1 1000 picofarads (pF).

Lead-free and RoHS compliant, AVX's UQ series RF and microwave MLC RF capacitors are available in seven voltages, ranging from 50 to 500 volts, and in eight capacitance tolerances, ranging from +/-0.1pf to +/-20 percent.

The series also 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 percent tin, and non-magnetic barrier/tin.

AVX's UQ series is rated for temperatures ranging from -55 to 125 degrees Celsius, and either meets or exceeds the requirements of EIA-198, MIL-PRF-55681, and MIL-PRF-123.
