The P0177NL is a coupled inductor array manufactured by Pulse Electronics, designed for surface-mount applications. It features two coils with an inductance of 37.3 µH and a tolerance of ±20%. The component operates within a temperature range of -40°C to +130°C. Electrical characteristics include a maximum DC resistance of 120 mΩ in series connection and 29.8 mΩ in parallel connection. Current ratings are specified at 1.89 A for series and 3.8 A for parallel configurations. The physical dimensions are 12.70 mm x 12.70 mm x 5.46 mm.

Arrays, Signal Transformers Feature Summary

• Dual-coil configuration supporting both series and parallel connectivity options
• Unshielded design suitable for general signal transformer applications
• Surface-mount technology (SMD) implementation for automated assembly

Arrays, Signal Transformers Applications

• Signal processing circuits requiring coupled inductance
• Power supply filtering stages utilizing parallel or series coil arrangements
• Electronic systems operating within extended industrial temperature ranges

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and availability status. Confirm RoHS compliance requirements with the manufacturer prior to ordering. Ensure ECAD models match the intended PCB footprint design. Check for any recent engineering change notices that may affect pinout or electrical specifications.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-coil inductor array is required for SMD assembly. Consider the 37.3 µH inductance value and current ratings for series or parallel operation. Evaluate the unshielded nature against electromagnetic interference constraints. Verify thermal performance within the -40°C to +130°C operating range for the target environment.

Arrays, Signal Transformers Part Context

This part belongs to the Polecat series from Pulse Electronics, categorized under arrays and signal transformers. It is distinct from other Pulse products such as the PE-51719NL current sensor or H5077NL LAN transformer. The P0177NL is specifically engineered as a coupled inductor array rather than a single-ended inductor or audio transformer.

Arrays, Signal Transformers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases or manufacturer cross-reference guides for potential alternatives. Ensure any replacement matches the 37.3 µH inductance, 12.70 mm x 12.70 mm footprint, and dual-coil configuration.
