EMI/RFI Tapped Filter
Features
• 8 EMI/RFI protection lines/package
• Stable resistor-capacitor network
• No signal delays
• Saves board space and component cost
• Suitable for PCMCIA interface cards
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

SCHEMATIC CONFIGURATION
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.
