RF capacitor

Vishay has released what it claims is the industry's first silicon-based surface mount RF capacitor available in the 0603 case size.

Based on a semiconductor process developed by Vishay, the new capacitor's construction reduces parasitic inductance while bringing self-resonant frequency values to frequencies two to three times higher than conventional RF capacitors.

The HPC0603A features SRF values up to 13 GHz over a range from 3.3 to 560 pF. The E12 values available in this range provide stable operation over a wide range of frequencies from 1 MHz to several GHz.

Parasitic inductance is a low 0.046 nH.

The capacitors feature high Q factors up to 4157, tolerances of ±1% or 0.05 pF, and low ESR values. Voltage options of 6, 10, 16 and 25 are available.

The device's high capacitance range and relatively compact package enable increases in circuit Q, transmission range, and reliability.
