PT400-1200HM

Fixed Inductors Overview

The Delevan PT400-1200HM is a fixed power inductor featuring a toroidal core and radial through-hole termination style. It provides an inductance of 400 µH with a tolerance of ±15%. The component has a maximum DC resistance of 250 mΩ and supports a current rating of 2.4 A. Designed for PCB mounting, it measures 44.45 mm in diameter and 19.81 mm in width. This shielded inductor belongs to the PTHZR series and is packaged in bulk quantities.

Fixed Inductors Feature Summary

• Toroidal core construction for efficient magnetic containment
• Radial leaded termination for standard PCB insertion
• Shielded design to minimize electromagnetic interference

Fixed Inductors Applications

• Power supply filtering circuits
• DC-DC converter input/output stages
• General power electronics applications

Fixed Inductors Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding lead content. Confirm that the specific order suffix corresponds to the required packaging format and terminal configuration. Ensure the procurement documentation explicitly states the 2.4 A current rating and 250 mΩ DCR limits to match circuit requirements. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and exact physical dimensions before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a high-current toroidal inductor with radial leads is required for power applications. The 400 µH value suits moderate frequency filtering tasks. Consider the physical footprint of 44.45 mm diameter for board space constraints. Verify thermal management needs given the 2.4 A rating and 250 mΩ resistance. Compare against unshielded alternatives if EMI sensitivity is low.

Fixed Inductors Part Context

This part belongs to the Delevan PTHZR series of fixed power inductors. These components are characterized by their toroidal geometry and radial pin arrangement, distinguishing them from surface-mount or axial variants within the broader product line. The series targets robust power handling in industrial and commercial equipment.

Fixed Inductors Replacement Considerations

PT400R-1750HM offers similar form factor but different electrical parameters. PT250R-1200HM shares the series but differs in inductance and dimensions. Direct substitutes require matching 400 µH, 2.4 A, and radial toroidal specifications.
