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.
