HM2102NL

Overview

The HM2102NL is a dual-channel common mode filter choke manufactured by Pulse Electronics, designed for surface mount applications. It features an inductance of 150 uH and a maximum DC resistance of 850 mOhms. The component operates within a temperature range of -40 C to +125 C and holds AEC-Q200 qualification. Its physical dimensions are 14.81 mm in length, 11.68 mm in width, and 5 mm in height, housed in an SMT-12 package.

Feature Summary

• Dual-channel configuration for simultaneous signal filtering
• AEC-Q200 qualified for automotive reliability standards
• High isolation voltage capability of 4.3 kV
• Surface mount design compatible with automated assembly

Applications

• Automotive battery management systems
• Audio signal processing circuits
• General signal transformer applications requiring common mode noise suppression

Procurement Notes

Verify current availability status as the component may be classified as End-of-Life (EOL) by some distributors. Confirm lead times and packaging types, such as tube or reel options, directly with authorized suppliers. Ensure compliance with RoHS directives and check for alternative packaging variants like the HM2102NLT if cut tape is required.

Selection Notes

Select this component when dual-channel common mode filtering is required in space-constrained designs. The 150 uH inductance and low DCR suit applications needing efficient noise attenuation without significant signal loss. Consider the 4.3 kV isolation rating for safety-critical interfaces. Verify that the SMT-12 footprint matches the PCB layout requirements.

Part Context

The HM2102NL belongs to the BMS series from Pulse Electronics, targeting robust performance in demanding environments. As a common mode choke, it suppresses electromagnetic interference on differential lines. The AEC-Q200 certification indicates suitability for automotive electronics, ensuring durability under thermal and mechanical stress typical in vehicle applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for the HM2102NLT variant if reel packaging is preferred over tubes. Consult manufacturer resources for cross-reference data regarding EOL status.
