Product Description
Note: CAMD’s P/Active T Filter is a higher performance, upgraded version of the original PRC200/210 series which provides 2KV ESD
protection, minimized lead inductance and parasitic capacitive effects (with added ground pins), and improved crosstalk and filter
performance characteristics at high data transmission rates. They exhibit almost ideal RC characteristics to 3 GHz. The PACT series
is recommended for all new designs.
CAMD’s P/Active T is a highly integrated thin film resistor-capacitor network designed to suppress EMI/RFI noise at
I/O ports of personal computers and peripherals, workstations, Local Area Network (LAN), Asynchronous Transfer
Mode (ATM), and Wide Area Network (WAN). The filter includes ESD protection circuitry which prevents device
destruction when subjected to ESD discharges of greater than 2KV. The ESD protection circuitry permits the filter to
operate on bipolar signals of up to ±6V. CAMD’s PACT is housed in a surface mount package suitable for bottom side
mounting to the board. This integrated network solution minimizes space and routing problems and improves reliability
and yields.
Why P/Active EMI/RFI filters? EMI/RFI filters are needed to suppress noise at low and high frequencies of the signal.
Ferrite beads, commonly 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. Also, conventional thick film-based EMI/RFI filters do not effectively suppress noise at high frequencies.
