Overview
The HM2171HL is a shielded audio and signal transformer from Pulse Electronics, designed for Battery Management Systems (BMS). It features an inductance range of 150 µH to 450 µH and supports an isolation voltage of 4300 Vrms. The component operates within a temperature range of -40°C to +125°C and includes two channels. It measures 14.81 mm in length, 11.68 mm in width, and 4.88 mm in height. The device is AEC-Q200 qualified and utilizes a tube packaging format.
Feature Summary
- AEC-Q200 qualification for automotive reliability standards
- High insulation voltage capability of 4300 Vrms
- Shielded construction to minimize electromagnetic interference
Applications
- Battery Management System (BMS) circuits
- Automotive electronic systems requiring high isolation
- Signal transformation in harsh thermal environments
Procurement Notes
Verify the specific inductance value required, as the datasheet indicates a range of 150 µH to 450 µH rather than a single fixed value. Confirm that the tube packaging aligns with your assembly line capabilities, as alternative reel or cut tape options may exist under different suffixes like HM2171HLT. Ensure the 4300 Vrms isolation rating meets your system safety requirements.
Selection Notes
Select this component when high-voltage isolation and automotive-grade reliability are critical for battery management applications. The wide operating temperature range supports deployment in demanding vehicular environments. Consider the physical dimensions and channel count to ensure compatibility with the target PCB layout and circuit topology.
Part Context
This part belongs to the BMS series by Pulse Electronics, specifically engineered for automotive battery management applications. It serves as a specialized signal transformer distinct from general-purpose LAN modules, focusing on robust isolation and thermal stability required for electric vehicle powertrain components.
Replacement Considerations
HM2171HLT is a documented substitute variant offering alternative packaging formats such as Reel, Cut Tape, or MouseReel while maintaining similar electrical specifications.
