B82731M2351A030

Overview

The B82731M2351A030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It functions as a two-line common mode choke designed to attenuate high-frequency interference while permitting DC and low-frequency signals to pass. The component features a rated inductance of 100 mH and a rated current of 350 mA. Its physical dimensions are 21.00 mm in length, 15.00 mm in width, with a maximum height of 20.50 mm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Current-compensated D-core construction for effective noise suppression
• Two-line design for dual-channel signal integrity
• High-temperature operation capability up to 125°C

Applications

• Power line filtering in industrial electronics
• Attenuation of high-frequency interference in communication circuits
• Signal conditioning where DC and low-frequency passage is required

Procurement Notes

Verify the manufacturer designation as EPCOS or TDK Electronics on the component body and datasheet. Confirm the specific suffix A030 corresponds to the radial lead configuration and 100 mH inductance value. Ensure the operating temperature range meets the application requirements of -40°C to +125°C before integration.

Selection Notes

Select this component when dual-line common mode noise suppression is required at 100 mH. The 350 mA rated current defines the operational limit. The D-core form factor suits applications needing compact vertical mounting. Verify that the 21x15 mm footprint fits the PCB layout constraints.

Part Context
