MSSAT type common mode chokes are designed for use in ISDN or analog networks as current-compensating circuit elements and have the following advantages:
- Low loss in a wide frequency range;
- Small volume. compact design (several windings on 1 core);
- Low leakage inductance and parasite capacitance.
Chokes are produced on the basis of toroidal cores wound of thin Co-based amorphous ribbon. Chokes are enclosed into plastic case and sealed with a compound. Case materials comply with UL94-VO class of fire resistance and the degree of 120°C of UL746B.
