HM2168NL

Overview

The HM2168NL is a dual-channel surface-mount transformer from Pulse Electronics, designed for Battery Management Systems (BMS). It features an inductance of 150 uH and a maximum DC resistance of 0.45 Ohms. The component operates within a temperature range of -40 C to +125 C and holds AEC-Q200 qualification. Its physical dimensions are defined by a specific footprint suitable for PCB mounting.

Feature Summary

• Dual primary and dual secondary winding configuration for isolated signal transmission
• AEC-Q200 qualified for automotive reliability standards
• Surface mount design optimized for automated assembly processes

Applications

• Battery Management System isolation
• Automotive electronic control units
• High-voltage battery monitoring circuits

Procurement Notes

Verify the specific datasheet revision and package tolerance against the manufacturing date code. Confirm that the 1CT:1CT ratio meets the circuit requirements. Ensure the operating environment stays within the specified thermal limits. Check for any recent product change notifications affecting pinout or materials.

Selection Notes

Select this component when high-frequency isolation is required for battery cell balancing or voltage sensing. The dual-channel architecture supports independent signal paths. Consider the physical size constraints and the need for AEC-Q200 compliance in automotive designs. Evaluate the DC resistance impact on signal integrity.

Part Context

This part belongs to the HM216x series of BMS transformers. It serves as a critical interface component for isolating high-voltage battery packs from low-voltage control electronics. The series is engineered for robust performance in harsh automotive environments.

Replacement Considerations

HM2168NLT is a tape-and-reel variant of the same electrical specification. Verify if the reel packaging is preferred over tube packaging for the production line.
