Feature Summary

• Functional dual-channel architecture providing isolated signal or power transfer between circuits
• High insulation capability rated at 4.3kV for safety-critical battery management applications
• AEC-Q200 qualified for automotive reliability and durability requirements

Applications

• Battery Management Systems (BMS)
• Automotive electronic control units requiring galvanic isolation
• Industrial power conversion interfaces

Procurement Notes

Verify the specific datasheet revision and pinout configuration before integration, as manufacturing updates may occur. Confirm that the 4.3kV rating aligns with system isolation requirements. Ensure PCB footprint dimensions match the 14.7 x 12.15 x 3.45 mm package specifications. Check for any recent Product Change Notifications (PCNs) affecting material composition or testing standards.

Selection Notes

Select this component when high-voltage isolation is required in compact automotive BMS designs. The dual-channel feature supports balanced circuit topologies. Verify thermal performance at maximum operating temperatures of 125°C. Compare against single-channel alternatives if space constraints allow for separate components. Ensure compatibility with surface-mount assembly processes.

Part Context

This transformer belongs to Pulse Electronics' BMS series, targeting automotive and industrial sectors. It addresses the need for reliable galvanic isolation in high-voltage battery environments. The AEC-Q200 certification ensures suitability for rigorous automotive quality standards. It complements other passive components in power management circuits.

Replacement Considerations

HM2167HLT is a related single-channel variant with similar electrical characteristics but different channel count. Verify functional equivalence regarding isolation voltage and inductance before substitution.
