Vishay Intertechnology Releases High-Frequency RF and Microwave Multilayer Ceramic Capacitors with High Q in 0402, 0603, and 0805 Case Sizes
MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of surface-mount multilayer ceramic chip capacitors (MLCCs) offering high self-resonance, a high Q factor of greater than or equal to 2000, and a low dissipation factor of less than or equal to 0.05 % for operation in high-frequency commercial applications.
With their low dissipation factor, devices in the VJ HIFREQ series are optimized for filter and matching networks, and amplifier and DC blocking circuits. The MLCCs reduce signal loss and energy consumption in power amplifier modules, VoIP networks, cellular base stations, GPS systems, and satellite, WiFi (802.11), and WiMAX (802.16) wireless communication.
Allowing designers to meet the size requirements of their specific applications, the VJ HIFREQ series is offered in 0402, 0603, and 0805 case sizes, with broad working voltages from 25 VDC to 250 VDC, and wide capacitance ranges from 1 pF to 1.5 nF. The devices offer tight tolerances to ±0.1 pF, an excellent aging rate of 0 % per decade, and an operating temperature range of - 55°C to + 125°C.
Manufactured in noble metal electrode technology (NME) with a wet build process, the capacitors are available with various RoHS-compliant termination finishes to meet the needs of the applications. Available options are nickel barrier with 100 % matte tin plate for reflow assembly (code "X"); silver-palladium for conductive epoxy assembly (code "E"); and non-magnetic for applications sensitive to magnetic interference (code "N").
Also, for those applications that demand it, the product is offered with a lead-bearing (minimum 4 %) termination finish (code "L").
Samples and production quantities of the new VJ HIFREQ MLCCs will be available in Q2 2012, with a lead time from 10 weeks FOB for larger orders. Pricing for U.S. delivery starts at only $0.06 per piece. Follow high-frequency ceramic capacitors from Vishay at http://twitter.com/vishayindust.
