PAC201QT

CAMD's P/Active T PAC201QT is a highly integrated thin film resistor-capacitor network designed to suppress EMI/RFI noise a I/O ports of personal computers and peripherals, workstations, Local Area Network (LAN), Asynchronous Transfer Mode (ATM), and Wide Area Network (WAN). PAC201QT includes ESD protection circuitry which prevents device destruction when subjected to ESD discharges of greater than 2KV. The ESD protection circuitry permits PAC201QT to operate on  ipolar signals of up to !à6V. CAMD's PACT is housed in a surface mount package suitable for bottom si 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 PAC201QT filters are needed to suppress noise at low and high frequencies of the signal. Ferrite beads, commonly used for EMI/RFI filtering, PAC201QT 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.
