TDK 100 mH Ferrite Power Line Choke Radial Mount 350 mA Max DC Current 4.5 Ω DC Resistance 250V AC B82731H2351A030

TDK B82731H2351A030 is a 100 mH ferrite power line choke designed for efficient suppression of common-mode interferences in electronic circuits. This power line choke uses a closed rectangular ferrite core with a 2-section winding to minimize stray inductance and leakage, offering high pulse strength and low whirring noise during operation.

This radial mount inductor is rated for a maximum DC current of 350 mA and a maximum DC resistance of 4.5 Ω, suitable for use in compact switch-mode power supplies and electronic ballasts for lamps. It is designed for operation across a wide temperature range from -40°C to 125°C, meeting demanding industrial, commercial, and electronic manufacturing standards.

With a maximum self-resonant frequency of 10 kHz and a maximum voltage rating of 250V AC, the B82731H series features a polycarbonate coil former with UL 94 V-0 flame retardant rating, ensuring safety and durability in PCB assemblies. Connections are via PC pin terminations with a lead diameter of 0.6 mm and 12.5 mm pitch, optimized for wave soldering processes.

Certified to UL, RoHS, IEC, ENEC, EN, and VDE standards, this power line choke assures compliance with global industry regulations and quality benchmarks. The choke's compact dimensions of 21 mm length, 20 mm depth, and 15.5 mm height make it an excellent choice for limited-space industrial and electronic applications.
