Tip and Ring Common Mode Filters

RoHS compliant
These economical filters are designed to help telecommunications equipment engineers meet FCC and CCITT requirements. Available in 1- or 2-line (2- or 4-wire) versions, Coilcraft tip and ring filters provide >20 dB attenuation of common mode noise over the 3 to 300 MHz frequency range.
  • Extremely economical design
  • Available in 1 or 2 line (2 or 4 wire) versions
  • Meet FCC and CCITT requirements
  • Greater than 20 dB common mode noise attenuation over 3 to 300 MHz range

Notes
  1. Frequency at which the differential mode attenuation equals 3 dB.
  2. Inductance is per winding.
  3. DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. For TRF 2000L, isolation (hipot) measured from pins 1,8 to 4,5 for one minute.
    For TRF 4000L, isolation (hipot) measured from pins 1,2,7,8 to pins 3,4,5,6 for one minute.
