Vishay Electro-Films 

## **Surface Mounted RF Capacitor HPC Replacement Part** 

## **FEATURES** 

- Industries highest SRF 

- Low DCR, high Q 

- Small size: 0.040" x 0.020" x 0.015" 

- S parameter files available upon request 

## **APPLICATIONS** 

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. 

- Lumped element filters 

- Impedance matching circuits 

- Decoupling and DC blocking 

- Smart cards 

- Other high Q RF circuitry 

The RFCS replaces the HPC product line. Additional values and form factors available upon request.
