Pulse Transformers Procurement Notes

Verify the specific suffix 'NLT' or 'NL' against the manufacturer's current datasheet to ensure correct packaging and compliance status. Confirm RoHS3 compliance requirements match your manufacturing standards. Check for any recent Product Change Notifications (PCNs) that may affect pinout or material composition before finalizing procurement orders.

Pulse Transformers Selection Notes

Select this component when high-frequency isolation and compact form factor are required. Ensure the 41 µH primary inductance aligns with the circuit's impedance matching needs. Verify that the 0.12 Ω DC resistance meets power loss constraints. Confirm that the 2.25 kV insulation rating satisfies safety isolation requirements for the target application environment.

Pulse Transformers Part Context

This part belongs to Pulse Electronics' portfolio of high-frequency wire-wound transformers. These components are engineered for reliable performance in demanding electronic environments. The series emphasizes miniaturization without compromising electrical isolation or signal fidelity, supporting modern compact device designs.

Pulse Transformers Replacement Considerations

Direct substitutes must match the 41 µH inductance, 0.12 Ω resistance, and 2.25 kV insulation rating. Verify footprint compatibility with the 14.50 mm x 17.65 mm dimensions. Cross-reference datasheets for equivalent frequency response characteristics and thermal limits.
