HDC205-101MTR

Fixed Inductors Overview

The HDC205-101MTR is a surface-mount power inductor from the HALO Electronics HDC205 series. It features an unshielded drum core wirewound construction with nonstandard dimensions of 13.05 mm x 9.4 mm x 6.35 mm. The component provides an inductance of 100 µH with a tolerance of 20%. It supports a maximum DC current of 1.2 A and has a maximum DC resistance of 280 mOhms. The self-resonant frequency is 9 MHz. The device operates within a temperature range of -40°C to +85°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for standard SMD applications
• Nonstandard footprint dimensions accommodating specific board layouts
• Fixed inductance value suitable for general power filtering

Fixed Inductors Applications

• DC-DC converter input/output filtering
• General purpose power supply circuits
• Signal processing choke applications

Fixed Inductors Procurement Notes

Verify the exact physical dimensions against the PCB footprint, as the package size is classified as nonstandard. Confirm that the 1.2 A current rating meets the peak load requirements of the target circuit. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the final assembly. Cross-reference the datasheet revision to ensure compatibility with existing design files.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to minimize cost and profile. The 100 µH value is appropriate for moderate frequency switching applications. Consider the 280 mOhm DCR impact on efficiency at full load. The nonstandard package requires careful mechanical clearance checks compared to standard EIA sizes.

Fixed Inductors Part Context

This part belongs to the HDC205 series of SMD Drum Core Inductors by HALO Electronics. The series offers low-cost miniature solutions for surface mount technology. Other variants in the series include different inductance values such as the HDC205-220MTR, which shares the same physical package but differs in electrical characteristics like inductance and resistance.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 100 µH inductance, 1.2 A current rating, and 280 mOhm resistance. Due to the nonstandard package dimensions (13.05 mm length), mechanical fitment is critical. Verify if alternative manufacturers offer equivalent performance in similar footprints.
