Product Description  
Note: CMD’s P/Active TFilters are 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 PAC T series is recommended for all new designs.  
CMD’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. CMD’s PAC T is housed in a surface mount package suitable for bottom side mounting to the board. This inte-  
grated 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.
