Vishay Intertechnology, Inc., is adding to its QUAD HIFREQ series of high-power surface-mount multilayer ceramic chip capacitors (MLCCs) with a new device in the quad 2525 case size. 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 (> 4000 at 10 MHz, 1 pF), ultra-low ESR down to 0.018 Ω, and DC voltage ratings up to 3600 V.
Based on an extremely stable ceramic dielectric and offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the Vishay Vitramon device released today 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 300 to 3600 V and a wide capacitance range from 1.0 to 2700 pF. The device offers tight tolerances to ± 0.1 pF, an excellent aging rate of 0 percent per decade, and an operating temperature range of 55 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 percent matte tin plate for reflow assembly (code "X"), and with a lead-bearing (minimum 4 %) termination finish (code "L"). The device is halogen-free and conforms to Vishay Green standards.
Samples and production quantities of the QUAD HIFREQ 2525 MLCC are available now, with a lead time of nine weeks for larger orders. Pricing for U.S. delivery only starts at $1.00 per piece.
