Product Description
Note: CAMDs P/Active Tapped Filters are a higher performance, upgraded versions of the original PRC201/211/221 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 charac-
teristics to 3GHz. The PACTF series is recommended for all new designs.
CAMDs P/Active Tapped Filter 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. CAMDs PACTF 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.
