The EPCOS B82721K2*U* series of power line chokes by TDK Corporation have been developed for use in home appliances such as washing machines, dishwashers, refrigerators, and heating control units. The plastic used (flame-retardant, compliant with UL 94 V-0) with a CTI value of 600 is certified in accordance with IEC 60335-1, Clause 30 (glow-wire and ball pressure test) and the complete encapsulation of the winding allows it to be used in environments with the highest degree of pollution.

The components have been certified by UL and VDE according to corresponding component standards (UL 1283, IEC 60938-2). These chokes are designed for a rated voltage of 250 V_AC and the range of inductance values extends from 0.4 µH to 47 µH.
