0402HM-190EGTS

Fixed Inductors Overview

The 0402HM-190EGTS is a fixed surface-mount inductor from Delta Electronics/Components, designed for high-frequency applications. It features an unshielded drum core wirewound construction with a ceramic core material. The component provides an inductance of 19 nH with a tolerance of ±2%. It has a rated current of 370 mA and a DC resistance of 270 mOhm. The self-resonant frequency is 4.5 GHz, tested at 100 MHz. Operating temperature range is -55°C to 125°C. Dimensions are 1.15mm x 0.70mm x 0.60mm (0402 package).

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for minimal magnetic interference.
• High self-resonant frequency capability up to 4.5 GHz.
• Ceramic core material ensures stable performance across wide temperature ranges.

Fixed Inductors Applications

• RF circuits requiring low inductance values.
• High-frequency signal filtering and impedance matching.
• Power supply output filtering in compact designs.

Fixed Inductors Procurement Notes

Verify the specific suffix 'EGTS' matches the required tolerance and packaging format. Confirm RoHS3 compliance status if environmental regulations apply. Check moisture sensitivity level (MSL 1) requirements for storage and handling procedures prior to assembly.

Fixed Inductors Selection Notes

Select this component when a small 0402 footprint is required with precise 19 nH inductance. Consider the 370 mA current rating against circuit load requirements. Ensure the unshielded nature does not cause EMI issues in dense layouts compared to shielded alternatives.

Fixed Inductors Part Context

Part of the 0402HM series, optimized for space-constrained surface mount applications. The HM series typically targets high-frequency performance with ceramic core stability. This specific model offers tight tolerance for precision RF tuning.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0402HM-190 variants with different tolerances or packaging, such as 0402HM-190EKTS if higher current is acceptable but note DCR differences. Cross-brand equivalents require matching 19nH, 0402 size, and >370mA rating.
