Datasheet

Vishay Intertechnology has announced the addition of a high-power surface-mount multilayer ceramic chip capacitor (MLCC) in the quad 2525 case size to its QUAD HIFREQ series. The MLCCs are designed for high-frequency RF applications in magnetic resonance imaging (MRI) coils and generators, RF instrumentation, telecomms base stations, lasers and military communications systems.

Based on an extremely stable ceramic dielectric, the QUAD HIFREQ 2525 features an ultra-high Q (more than 4000 at 10MHz and 1pF), ultra-low ESR down to 0.018Ω and DC voltage ratings up to 3600V. Offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the 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 of 300-3600V and a wide capacitance range of 1.0-2700pF. The device offers tight tolerances to ±0.1pF, an excellent aging rate of 0% per decade and an operating temperature range from -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% 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.
