Features

  • 8 EMI/RFI protection lines/package  Stable resistor-capacitor network  No signal delays  Saves board space and component cost  Suitable for PCMCIA interface cards Product Description CAMD’s PRC201/211/221 Tapped 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. This integrated thin film resistor-capacitor network is 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. Why thin film EMI/RFI filters? EMI/RFI filters are needed to suppress noise at low and high frequencies of the signal. Ferrite beads 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

Applications

 EMI/RFI Filter  Low Pass Filter C1190600 SCHEMATIC CONFIGURATION EMI/RFI filtering. Conventional thick film-based EMI/RFI filters do not effectively suppress noise at high frequen- cies due to the fact that EMI/RFI filters using thick film technology have high parasitic inductance which becomes the dominant component of the capacitor’s impedance past resonance, and therefore significantly affects high frequency performance of the filter. CAMD’s PRC201/211/221 Tapped Filter is fabricated on a silicon substrate using advanced thin film technology. These EMI/RFI filters have very low parasitic inductance and suppress EMI/RFI noise at low and high frequencies to well above 1000 MHz. 20 19 18 17 16 15 14 13 12 11 12 3 4 5 6789 10 NOITAMROFNIGNIREDROTRAPDRADNATS egakcaPr ebmuNtraPgniredrO edoCCRs niPe lytSs ebuTl eeR&epaTg nikraMtraP F051/0010 2C IOST /M051/K001102CRPR /M051/K001102CRPM 051/K001102CRP F101/0330 2C IOST /M101/K033102CRPR /M101/K033102CRPM 101/K033102CRP F152/0330 2C IOST /M152/K033102CRPR /M152/K033102CRPM 152/K033102CRP F074/0330 2C IOST /M074/K033102CRPR /M074/K033102CRPM 074/K033102CRP F122/0930 2C IOST /M122/K093102CRPR /M122/K093102CRPM 122/K093102CRP F074/0740 2C IOST /M074/K074102CRPR /M074/K074102CRPM 074/K074102CRP F005/0570 2C IOST /M005/K057102CRPR /M005/K057102CRPM 005/K057102CRP F101/1010 2C IOST /M101/K101102CRPR /M101/K101102CRPM 101/K101102CRP F151/1010 2C IOST /M151/K101102CRPR /M151/K101102CRPM 151/K101102CRP
