Wurth’s WE-ExB series is the double core choke made of MnZn and NiZn. Its insertion loss has a range of effect over a broader frequency range than does a single NiZn or MnZn core. Compared with previously available current-compensated line chokes, this means a 70% greater insertion loss in the low frequency range (150 kHz to 4 MHz) and a 30% greater insertion loss in the high frequency range (4 MHz to 30 MHz). This current-compensated common mode choke is particularly suited for network applications with a broad interference spectrum in EMC, network, or common-mode filters, especially in power electronics and motor interference suppression.
