DESCRIPTION

P2910 is a  microprofile current compensated quad
choke to assist ISDN S

o

  equipments meet EMC

requirements. The winding inductance is
maintained at a more constant level than is
achievable with strip-wound cores over the
important decade 100kHz – 1MHz, and leakage
inductance between the windings is exceptionally
low.
