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.
