Vishay – QUAD HiFREQ Series: Surface Mount Multilayer Ceramic Capacitors for RF Power Applications

Vishay Vitramon extended its QUAD HiFREQ product line, introducing a 3838 case size to the already existing 0505, 1111 and 2525 cases.

Its special ceramic and electrode materials yield an extremely low ESR, high Q, and high SRF and PRF, with voltage ratings from 300VDC to 7200VDC, designed for high frequency RF applications in telecommunications, medical, military, industrial equipment and instrumentation.

The devices are optimized for a wide range of high frequency applications, including MRI coils and generators, RF instrumentation, and impedance matching networks.

In addition, Vishay Vitramon offers its HiFREQ line of surface mount, high frequency MLCCs in the 0402, 0603, and 0805 case sizes, which are ideal for commercial applications such as VoIP networks, cellular base stations, satellite, WiFi (802.11), and WiMAX (802.16) wireless communication.

The QUAD HiFREQ series offers broad working voltages from 200V to 7200V, and wide capacitance ranges from 1.0pF to 2700pF.

The devices offer tight tolerances to ±0.05pF, an excellent aging rate of 0% 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 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”) and with the new copper termination (code “C“) for non-magnetic applications.

The devices are halogen-free and conform to Vishay “Green” standards.
