Product Description

CAMD’s PRC200/210 Tapped Filter is specifically

designed to suppress EMI/RFI noise at I/O ports of

personal computers and engineering workstations, Local

Area Network (LAN), Asynchronous Transfer Mode

(ATM), Wide Area Network (WAN), and peripheral

accessories. This integrated thin film resistor capacitor

network is available in miniature surface mount pack-

ages which minimizes space and routing problems and

improves reliability and yields.

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 PRC200/210 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.
