Vishay Intertechnology have today announced the new QUAD HIFREQ series of high-power surface-mount multilayer ceramic chip capacitors in the quad 0505 and 1111 case sizes. Featuring ultra-high Q > 2000, ultra-low ESR down to 0.01 Ω, and voltage ratings to 1500 V, the new QUAD HIFREQ series MLCCs are specifically designed for high-frequency RF applications in telecommunications, medical, military, and industrial equipment and instrumentation.
Offering broad working voltages from 200 V to 1500 V, the new QUAD HIFREQ series features wide capacitance ranges from 1.0 pF to 1000 pF. Designed to provide reliable performance in critical applications such as filter and impedance matching networks, timing circuits, mixers, and oscillators, the new devices are based on an extremely stable ceramic dielectric and offering high serial resonant frequency and parallel resonant frequency.
The QUAD HIFREQ series devices offer tight tolerances to ± 0.1 pF, an excellent aging rate of 0 % per decade, and an operating temperature range of -55 °C to +125 °C. The halogen-free, RoHS-compliant capacitors are manufactured in noble metal electrode technology with a wet build process.
The new MLCCs conform to Vishay "Green" standards when manufactured with nickel barrier terminations with 100 % matte tin plate for reflow assembly (code "X"). Additionally, the capacitors are available with a lead-bearing (minimum 4 %) termination finish (code "L").
Samples and production quantities of the new QUAD HIFREQ MLCCs are available now, with a lead time of 12 weeks for larger orders.
