Vishay Intros HPC0402A Silicon-Based Capacitors

Vishay Intertechnology Inc. (Malvern, PA) announced silicon-based HPC0402A RF capacitors for circuitry in cellular phones and other wireless communications systems. Built on a proprietary Vishay process, the capacitors provide stability over a wide frequency range, high Q factors, low ESR values and accurate dimensions. Typical applications include wireless communications, GPS, VCO, filter and matching networking, and power amplifiers.

The HPC0402A is available in 6V, 10V, 16V and 25V options. Overall capacitance ranges from 0.6pF to 180pF with tight tolerance to ±1% or 0.05pF. The HPC0402A measures 0.040in x 0.020in x 0.016in (1.02mm x 0.51mm x 0.40mm). The device features a temperature coefficient of capacitance of ±30ppm/°C over an operating temperature range of -55°C to +125°C, a lifetime of 1,000 hours at +125°C at twice the rated power, and resistance to moisture and thermal shock.
