These economical ﬁlters are designed to help telecom-

munications equipment engineers meet FCC and CCITT

requirements. Available in 1 or 2 line (2 or 4 wire) versions,

Coilcraft tip and ring ﬁlters provide >15 dB attenuation of com-

mon mode noise over the 3 Hz to 300 MHz frequency range.

Part number:

TRF 2000L (1-line)

TRF 4000L (2-line)

Minimum inductance:

Rated current:

20 µH

500 mA

DC resistance:

Dielectric strength¹:
