Specifications subject to change without notice.
Document 257-1
Revised 12/03/02
These high performance, high current tip and ring filters
are designed to help telecom equipment engineers
meet FCC and CCITT requirements.
They provide up to 35 dB attenuation of common mode
noise over a broad frequency range, while the low
differential mode attenuation assures excellent signal
integrity. The filters come in 2- and 1-line versions and
provide 1500 Vrms isolation between pairs.
