Thin Film Wirebondable RF Capacitor

Product may not be to scale

RFCS series of thin film capacitors on silicon are designed

for RF circuits that require exceptional performance at

frequencies up to 20 GHz. The unique structure of the RFCS

capacitors is based on thin-film electrodes deposited on a

highly conductive silicon substrate. This unique structure is

characterized by low parasitic inductance allowing the

capacitors to maintain their performance to higher

frequencies than other technologies.

The RFCS replaces the HPC product line.
