PA0390.102NLT

Fixed Inductors Overview

The PA0390.102NLT is a fixed surface-mount power inductor manufactured by Pulse Electronics, belonging to the 102NL series. It features an unshielded wirewound construction with a non-standard package footprint. The component provides an inductance of 1.2 µH with a tolerance of ±20%. It supports a maximum DC current of 4.4 A and exhibits a maximum DC resistance of 17.7 mOhms. Designed for commercial applications, it operates within a temperature range of -40°C to +125°C and meets RoHS compliance standards.

Fixed Inductors Feature Summary

• Unshielded wirewound design for specific magnetic field requirements
• High current handling capability suitable for power circuits
• RoHS compliant manufacturing process

Fixed Inductors Applications

• Commercial power supply modules
• DC-DC converter input/output filtering
• General purpose power electronics

Fixed Inductors Procurement Notes

Verify the exact physical dimensions against the official datasheet before PCB layout finalization, as the package is classified as non-standard. Confirm that the unshielded nature aligns with the electromagnetic interference constraints of the target application environment. Ensure the selected distributor is an authorized partner to guarantee component authenticity and traceability.

Fixed Inductors Selection Notes

Select this component when a 1.2 µH inductance value is required with a 4.4 A current rating. The unshielded construction distinguishes it from shielded alternatives in the same series. Consider the 17.7 mOhm DCR for efficiency calculations. This part is suitable for commercial grade environments rather than automotive or high-reliability industrial sectors requiring AEC-Q200 certification.

Fixed Inductors Part Context

This component is part of the 102NL series from Pulse Electronics, which has been transitioned to the PA0390 naming convention. The 'NL' suffix denotes RoHS compliance. It serves as a direct replacement for older 102NL designations in updated designs, maintaining the same electrical characteristics while adhering to modern environmental regulations.

Fixed Inductors Replacement Considerations

The PA0390.102NLT is the designated replacement for the legacy 102NL.102 model. Designers updating existing boards should verify pin compatibility and thermal performance, as the physical package remains consistent with the original series specifications.
