Procurement Notes

Verify the specific ordering suffix against official documentation, as variations such as NLT or HLT may indicate differences in packaging or tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors prior to procurement. Ensure the obsolete status does not impact long-term supply chain stability for production runs.

Selection Notes

Select this component when a 155 nH inductance value is required alongside a minimum 31 A current rating. Evaluate the thermal performance at 130°C maximum operating temperature to ensure compatibility with the system's heat dissipation strategy. Consider the 10.2 mm footprint for adequate spacing on the printed circuit board relative to adjacent components.
