PF0553.332NLT

Arrays, Signal Transformers Overview

The PF0553.332NLT is a shielded dual-coil power inductor array from Pulse Electronics, designed for surface-mount applications. It features a ferrite core and offers an inductance of 3.3 µH per coil with a tolerance of ±20%. In parallel configuration, the total inductance is 1.65 µH with a maximum DC resistance of 9.7 mΩ and a rated current of 8.1 A. The saturation current is 9.5 A in parallel mode. Dimensions are 4.50 mm x 4.50 mm x 1.80 mm max, operating between -40°C and 125°C.

Arrays, Signal Transformers Feature Summary

• Dual-winding shielded design minimizes electromagnetic interference
• Low profile construction suitable for space-constrained boards
• High saturation current capability for robust power handling

Arrays, Signal Transformers Applications

• Point-of-load voltage regulation circuits
• DC-DC converter output filtering
• Multi-phase power supply interleaving

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'NLT' to ensure compatibility with tape-and-reel automated assembly processes. Confirm that the 1.80 mm maximum height fits within the designated PCB clearance constraints. Cross-reference the manufacturer part number against official distributor catalogs to avoid confusion with similar series variants or non-shielded alternatives.

Arrays, Signal Transformers Selection Notes

Select this component when a compact dual-inductor solution is required for high-current synchronous buck converters. The low DCR reduces conduction losses, while the shielded structure prevents magnetic coupling issues with nearby sensitive components. Ensure the thermal environment supports the 125°C rating and verify footprint compatibility during layout.

Arrays, Signal Transformers Part Context

This part belongs to the PF0553NL series of SMT power inductors. It shares the same mechanical footprint and shielding technology as other members like PF0553.153NLT but differs in electrical specifications. The series is engineered for high-density power management systems requiring reliable performance under varying load conditions.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include PF0553.153NLT for higher inductance needs or PF0553.222NL for different current ratings. Verify pinout and dimensional compatibility before swapping. Consult manufacturer cross-reference guides for equivalent parts from other suppliers.
