Thin Film Surface Mounted 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.
