Vishay Intertechnology Inc. has unveiled a device in the quad 2525 case size, adding to its QUAD HIFREQ series of high-power surface-mount multi-layer 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 QUAD HIFREQ 2525 case device features an ultra-high Q ( > 4,000 at 10MHz, 1pF), ultra-low ESR down to 0.018Ω, and DC voltage ratings up to 3.6kV.

Based on a stable ceramic dielectric and offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the Vishay Vitramon device is 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.

The QUAD HIFREQ 2525 device offers a broad working voltage from 300V to 3.6kV and a wide capacitance range from 1pF to 2,700pF. The device offers tight tolerances to ± 0.1pF, an ageing rate of 0 per cent per decade, and an operating temperature range of -55°C to 125°C.

Manufactured in noble metal electrode (NME) technology with a wet build process, the QUAD HIFREQ 2525 capacitor is available with RoHS-compliant nickel barrier terminations with 100 per cent matte tin plate for reflow assembly (code "X"), and with a lead-bearing (minimum 4 per cent) termination finish (code "L"). The device is halogen-free and conforms to Vishay Green standards.
