Recently, Vishay Intertechnology, Inc. (NYSE: VSH) unveiled a groundbreaking series of surface-mount multilayer ceramic chip capacitors (MLCCs) called the VJ HIFREQ. This new line is specifically designed for high-frequency commercial applications, offering exceptional performance with a high self-resonant frequency and a Q factor exceeding 2000. Additionally, it maintains a low dielectric loss angle of less than 0.05%, making it ideal for demanding RF environments.

The VJ HIFREQ series is well-suited for use in filter and matching networks, amplifiers, and DC isolation circuits. Its low dielectric loss helps reduce signal loss and power consumption in various applications, including power amplifier modules, VoIP systems, mobile base stations, GPS devices, satellite communications, WiFi (802.11), and WiMAX (802.16) wireless technologies.

Available in three compact sizes—0402, 0603, and 0805—the VJ HIFREQ series gives designers flexibility to meet specific application requirements. It operates from 25 VDC to 250 VDC and offers capacitance values ranging from 1 pF to 1.5 nF. The capacitors feature a tight tolerance of ±0.1 pF, no aging over time, and can function within an operating temperature range of -55°C to 125°C.

These capacitors utilize advanced precious metal electrode (NME) technology combined with wet manufacturing processes. This ensures a variety of RoHS-compliant termination options, such as a nickel grid with 100% matte tin (code "X") for reflow soldering, silver palladium (code "E") for conductive resin assembly, and a non-inductive model (code "N") that is sensitive to electromagnetic interference.

For specialized applications, leaded versions (code "L") are also available, featuring a minimum of 4% lead content. This makes them suitable for certain legacy or custom designs where leaded components are required.

Vishay plans to begin sampling the VJ HIFREQ MLCCs in the second quarter of 2012, with mass production following shortly after. Orders over a certain volume will have a lead time of ten weeks for offshore shipments, ensuring timely delivery for manufacturers and system integrators.
