HM1238NL

Overview

The HM1238NL is a pulse transformer manufactured by Pulse Electronics, designed for battery management applications. It features a common mode choke (CMC) configuration with a turns ratio of 1:1 and an inductance of 300µH. The component supports AEC-Q200 qualification standards, ensuring reliability for automotive environments. It utilizes surface mount technology with a tube packaging format. Physical dimensions are specified as 10.50mm length, 8.38mm width, and a maximum height of 4.25mm. The device exhibits a maximum DC resistance of 500 mOhms.

Feature Summary

AEC-Q200 qualified for automotive reliability
Integrated common mode choke functionality
Surface mount construction for automated assembly

Applications

Battery Management Systems (BMS)
Automotive electronic circuits
Signal isolation interfaces

Procurement Notes

Verify the specific revision status against the manufacturer's latest documentation to ensure compliance with current design requirements. Confirm that the surface mount package dimensions align with the printed circuit board layout constraints. Ensure the procurement channel provides valid traceability records for AEC-Q200 certified components. Validate that the tube packaging format matches the available pick-and-place equipment specifications.

Selection Notes

Select this component when a 300µH inductance value is required for common mode noise suppression in signal lines. The 1:1 turns ratio makes it suitable for direct signal coupling without voltage transformation. Consider the physical footprint of 10.50mm by 8.38mm during the initial PCB layout phase. Verify thermal performance requirements against the maximum operating temperature limits defined in the official datasheet.

Part Context

This part belongs to the Pulse Transformers product line from Pulse Electronics, specifically categorized under audio and signal transformers. It is engineered for use in modules requiring isolated signal transmission within power management systems.
