Vishay Intertechnology has rolled out its latest series of high-power surface-mount multi-layer ceramic chip capacitors (MLCCs) in the quad 0505 and 1111 case sizes. Designed for high-frequency RF applications, the QUAD HIFREQ series features ultra-high Q greater than 2000, ultra-low ESR down to 0.01次, and voltage ratings to 1500V.

Based on an extremely stable ceramic dielectric and offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the Vishay Vitramon devices released today are designed to provide reliable performance in critical applications such as filter and impedance matching networks, timing circuits, mixers, and oscillators.

The QUAD HIFREQ series offers broad working voltages from 200V to 1500V and wide capacitance ranges from 1.0pF to 1000pF. The devices offer tight tolerances to 0.1pF, an excellent ageing rate of 0per cent per decade, and an operating temperature range of -55∼C to 125∼C.

Manufactured in noble metal electrode technology (NME) with a wet build process, the capacitors are halogen-free, RoHS-compliant, and in conformance with Vishay "Green" standards when manufactured with nickel barrier terminations with 100per cent matte tin plate for reflow assembly (code "X"). Additionally, the capacitors are available with a lead-bearing (minimum 4 per cent) termination finish (code "L").
