Product Description

CAMD’s PRC201/211/221 Tapped Filter is designed to

suppress EMI/RFI noise on high speed data lines and at

I/O ports of PCMCIA fax/modem and LAN type cards.

This integrated thin film resistor-capacitor network is

housed in a ultra low profile, surface mount package

suitable for bottom side mounting to the card which

minimizes space and routing problems and improves

reliability.

Why thin film EMI/RFI filters? EMI/RFI filters are needed

to suppress noise at low and high frequencies of the

signal. Ferrite beads used for EMI/RFI filtering are bulky

and ineffective at low frequencies and have saturation

problems at high frequencies. Resistor-capacitor

networks offer the best technical approach for effective

EMI/RFI filtering. Conventional thick film-based EMI/RFI

filters do not effectively suppress noise at high frequen-

cies due to the fact that EMI/RFI filters using thick film

technology have high parasitic inductance which

becomes the dominant component of the capacitor’s

impedance past resonance, and therefore significantly

affects high frequency performance of the filter.

CAMD’s PRC201/211/221 Tapped Filter is fabricated on

a silicon substrate using advanced thin film technology.

These EMI/RFI filters have very low parasitic inductance

and suppress EMI/RFI noise at low and high frequencies

to well above 1000 MHz.
