TDK 22 mH Ferrite Power Line Choke Radial Mount 800 mA DC Current 800 mΩ DC Resistance Max SRF 10 kHz 250V AC B82731M2801A030

TDK B82731M2801A030 is a 22 mH ferrite power line choke designed for efficient suppression of common-mode interferences in power lines. It features a radial mount style and supports a maximum DC current of 800 mA and a DC resistance of 800 mΩ. The choke operates with a maximum self-resonant frequency of 10 kHz and withstands voltages up to 250 V AC.

This power line choke incorporates a closed rectangular ferrite core with a two-section winding that reduces stray inductance to approximately 1%, ensuring symmetrical interference suppression and low leakage currents. The coil former is made from polycarbonate rated UL 94 V-0 and is not encapsulated, providing clearance and creepage distances of at least 3 mm for enhanced safety.

Its compact dimensions (21 mm length, 20 mm height, and 15 mm depth) and 0.6 mm lead diameter with 12.5 mm lead pitch facilitate wave soldering and PCB mounting. The device demonstrates high pulse strength and low whirring noise, making it suitable for use in compact switch-mode power supplies and electronic ballasts for lamps.

Applications for this choke include suppression of common-mode interference in various electronic circuits, particularly in industrial and commercial electronics, HVAC systems, manufacturing automation, and water treatment controls. The component complies with stringent safety and environmental standards including EN, UL, ENEC, VDE, and RoHS.

The product is supplied in box packaging and originates from Hungary. Its high-quality ferrite core material guarantees durability and reliable performance under the specified temperature range from -40°C to 125°C.

Inductance rating of 22 mH suitable for common-mode interference suppression. Maximum DC current of 800 mA with precise resistance characteristics. Radial mount style with PC pin termination for secure soldering. High self-resonant frequency of 10 kHz enhances filtering capabilities.

Compliant with international safety standards ensuring quality and reliability. Compact size allows easy integration in dense electronic assemblies. Low leakage and high pulse strength reduce operational noise and improve circuit stability.
