Vishay Intertechnology Enhances QUAD HIFREQ Series MLCCs for Telecom, Medical, Military, and Industrial Equipment

Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has enhanced its QUAD HIFREQ series of high-power surface-mount multilayer ceramic chip capacitors (MLCCs). Designed for high-frequency RF applications in magnetic resonance imaging (MRI) coils and generators, RF instrumentation, telecom base stations, lasers, and military communications systems, the improved devices feature an extended capacitance range down to 0.1 pF in the 0505 case size and 0.2 pF in the 1111 case size; tighter capacitance tolerance down to ± 0.05 pF (code “V”); and new non-magnetic copper terminations (code “C”).

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

Manufactured in noble metal electrode (NME) technology with a wet build process, the QUAD HIFREQ series features a broad working voltage range from 200 V to 7200 V and a wide capacitance range from 0.1 pF to 5100 pF in the quad 0505, 1111, 2525, and 3838 case sizes. The devices offer an excellent aging rate of 0 % per decade and an operating temperature range of -55 °C to +125 °C.

In addition to the new non-magnetic copper terminations, which provide improved solder fillet characteristics for reflow soldering assembly, the capacitors are available with RoHS-compliant nickel barrier terminations with 100 % matte tin plate for reflow assembly (code “X”), and with a lead-bearing (minimum 4 %) termination finish (code “L”). The Vishay Green devices are halogen-free.

Samples and production quantities of the QUAD HIFREQ MLCCs are available now, with a lead time of nine weeks for larger orders.
