MECHANICALS
Bel introduces a new ISDN "U" Interface
transformer. The transformer is designed
to be used with the Motorola ISDN "U"
Interface Chip MC145572.
* Dielectric Strength - 1500 Vrms measured Primary to
Secondary. Meets or exceeds requirements of
CAN/CSA-C22.2 No.225(M90) &
UL Std. No. 1950 2nd ed.
* Part Number 0559-6204-00 varies only in its additional
insulation.
