The document introduces CAMD PRC201/211/221 EMI/RFI Tapped Filter. The filter is designed to suppress EMI/RFI noise on high speed data lines and at I/O ports of PCMCIA fax/modem and LAN type cards. The filter is a thin film resistor-capacitor network housed in a ultra low profile, surface mount package suitable for bottom side mounting to the card which minimizes space and routing problems and improves reliability.
The PRC201/211/221 series are thin‑film EMI/RFI tapped filters designed to suppress noise on high‑speed data lines and I/O ports of PCMCIA fax/modem and LAN cards. Their low‑profile surface‑mount packages minimize board space and improve reliability.
The datasheet lists standard and non‑standard part ordering information, electrical specifications such as tolerance, temperature range, and power rating, as well as standard and non‑standard resistance and capacitance values.
