Vishay VJ HIFREQ ceramic chip capacitor range

Vishay has introduced a series of surface-mount multilayer ceramic chip capacitors offering high self-resonance, a high Q factor of ≥2000 and a low dissipation factor of ≤0.05 % for operation in high-frequency commercial applications.

With their low dissipation factor, devices in the VJ HIFREQ series are optimised for filter and matching networks and amplifier and DC blocking circuits. They reduce signal loss and energy consumption in power amplifier modules, VoIP networks, cellular base stations, GPS systems and satellite, Wi-Fi (802.11) and WiMAX (802.16) wireless communication.

The series is offered in 0402, 0603 and 0805 case sizes, with broad working voltages from 25 to 250 VDC and wide capacitance ranges from 1 pF to 1.5 nF. The devices offer tight tolerances to ±0.1 pF, a good ageing rate of 0% per decade and an operating temperature range of -55 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.
