- Signal filtering in noisy environments
Procurement Notes
Verify the specific datasheet version for the HM2108NL to confirm exact electrical tolerances and mechanical dimensions before finalizing designs. Ensure compatibility with peak reflow temperatures specified by Pulse Electronics. Cross-reference part numbers carefully, as suffixes may indicate packaging variations rather than functional changes. Confirm AEC-Q200 certification status directly from official documentation.
Selection Notes
Select this component when high isolation and automotive-grade durability are required for signal lines. The 135 µH inductance provides effective common mode noise suppression. Consider the surface mount package constraints during PCB layout. Verify that the operating temperature range meets the specific environmental demands of the target application.
Part Context
This component belongs to the MDL series of signal transformers and common mode chokes from Pulse Electronics. It is engineered specifically for robust performance in data communication and automotive sectors. The series emphasizes compact form factors combined with high electrical isolation capabilities.
Replacement Considerations
Check for direct substitutes within the same MDL series or other AEC-Q200 qualified common mode chokes with similar 135 µH inductance and 4.3 kV isolation ratings. Ensure pinout and footprint compatibility if replacing on existing boards.
