The B82721K2*U* series of RoHS-compatible power line chokes are encapsulated in a flame-retardant plastic compliant with UL 94 V-0 with a CTI value of 600 and is certified in accordance with IEC 60335-1, clause 30 for glow-wire and ball pressure testing. The complete encapsulation of the winding allows it to be used in environments with the highest degree of pollution.

The EPCOS chokes are designed for a rated voltage of 250 V AC and the range of inductance values extends from 0.4 mH to 47 mH. Depending on the inductance, their rated currents range from 0.4 A to 2.8 A, while the rated ambient temperature is +70 °C. The dimensions for all versions are 13.2 mm x 18.2 mm x 20 mm.

The components have been certified by UL and VDE according to corresponding component standards (UL 1283, IEC 60938-2).Main applications
