Product Description

TDK B82731M2501A030 Power Line Choke is a high-quality, radial mount inductor designed for efficient suppression of common-mode interferences in electronic circuits.

Built with a ferrite core and a closed rectangular design with a 2-section winding, this choke offers a low leakage inductance with high resonance frequency, improving noise reduction in compact switch-mode power applications and electronic ballasts in lamps.

The choke operates with a maximum DC current of 500 mA, maximum DC resistance of 2 Ω, and a maximum operating voltage of 250V AC. It has a self-resonant frequency of 10 kHz which suits a variety of electronic applications requiring high-frequency noise filtering.

It features a robust closed polycarbonate coil former (UL 94 V-0 rated) without encapsulation, providing clearance and creepage distances greater than or equal to 3 mm, enhancing safety and reliability during PCB assembly.

The component has a compact size with dimensions of 21mm length, 20mm height, and 15mm depth, and uses PC pin terminations with a lead pitch of 12.5mm and lead diameter of 0.6mm, facilitating easy integration into printed circuit boards through wave soldering.

This choke boasts excellent pulse strength and low acoustic noise, making it suitable for professional electronic manufacturing, HVAC systems, industrial equipment, and laboratory electronic components where reliable noise suppression is critical.
