Product Description

TDK B82731M2182A030 is a 3.3 mH Ferrite Power Line Choke designed specifically for effective suppression of common-mode interferences in electronic circuits. Constructed with a closed rectangular ferrite core and a two-section winding, this choke provides a high resonance frequency of 10 kHz, supporting compact switch-mode power applications such as power supplies and electronic ballasts in lamps.

The device supports a maximum DC current of 1.8 A with a DC resistance of 140 mΩ, operating reliably up to 125°C and a maximum voltage of 250 V AC. Its radial mount type lends itself to easy integration on printed circuit boards via PC pin termination style. The lead diameter is 0.6 mm with a pitch of 12.5 mm.

Physical dimensions include a length of 21 mm, height of 20 mm, and depth of 15 mm, suitable for compact electronic assemblies. The product features low leakage due to the closed core shape, low whirring noise, and high pulse strength, making it suited for industrial and commercial electronics requiring high electromagnetic interference suppression.

B82731M series chokes by TDK are RoHS and EN compliant, adhering to ENEC, IEC, UL, and VDE standards. Manufactured in Hungary, these inductors are supplied in box packaging for secure shipment.

Closed rectangular ferrite core with 2-section winding. Approximate 1% stray inductance ensuring symmetrical interference suppression. High resonance frequency of 10 kHz for effective noise filtering. Robust construction with polycarbonate coil former (UL 94 V-0) without encapsulation.

Suitable for wave soldering and industrial applications requiring EMI suppression. Compact dimensions and radial mounting style for efficient PCB assembly. Certified to multiple international standards ensuring quality and reliability.

This power line choke is ideal for integration in industrial, laboratory, and commercial electronic equipment, particularly in power supplies and lighting systems. Explore more electronic components and inductors on EnvMart for your design needs.
