EMC Components: Current-Compensated Ring-Core Chokes for Home Appliances

Untitled-1

TDK Corporation has presented a new series of EPCOS ring-core double chokes. The new B82721K2*U* series of RoHS-compatible power line chokes have been developed in particular for use in home appliances such as washing machines and 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.

How To Work Safely with High‑Voltage Test & Measurement Equipment

This white paper describes an alternative approach to calibrating high-voltage systems and provides meter and probe safety considerations and general guidance for safely operating high-voltage equipment.

These 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

  • Power supplies, home appliances and heating control units

Main features and benefits

  • Compatibility with applications in accordance with IEC 60335-2 with CTI >250 and degree of pollution 3
  • High rated current and rated temperature
