Vishay Introduces Industry's First MLCC for High Frequency RF and Microwave

Vishay Intertechnology, Inc. announced that it has introduced the industry's first surface mount multilayer ceramic chip capacitor (MLCC) for high frequency RF and microwave applications - the VitramonVJ HIFREQ HT series, which operates over a temperature range of +200 C. A base station for the communication and defense communications systems, Vishay's VitramonVJ HIFREQ HT series offers four compact size, having a low Q and ultra-high ESR.

For high-power communication transmitters and high-frequency inverters exposed to +175°C or higher, designers have previously had to rely on MLCCs limited to +150°C. Today's devices have an operating temperature range of -55°C to +200°C, providing long-term reliability in such applications.

The MLCC has a larger operating voltage range from 16V to 500V and a larger capacitance range from 0.1pF to 3.3nF with a tolerance of only ±0.05 pF. The device provides excellent aging at 0% per decade and high ESD tolerance to prevent high voltage transients.

These capacitors are manufactured using a wet metal fabrication process using noble metal electrode (NME) technology and are available in a variety of RoHS-compliant termination finishes, including: 100% tin plated for reflow soldering. Nickel barrier (codenamed "X"), a non-magnetic copper barrier (codenamed "C") for magnetic interference sensitive applications, and silver palladium (codenamed "E") for conductive epoxy components.
