0402HM-120EHTS

Fixed Inductors Overview

The 0402HM-120EHTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a 12 nH nominal inductance with ±3% tolerance. It utilizes an unshielded drum core wirewound construction on a ceramic substrate. The component supports a rated current of 500 mA and exhibits a DC resistance of 140 mΩ. Designed for high-frequency applications, it achieves a self-resonant frequency of 4.4 GHz when tested at 250 MHz. The device operates within a temperature range of -55°C to 125°C and is housed in a compact 0402 (1005 metric) package measuring 1.15mm x 0.70mm x 0.60mm.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for minimal magnetic interference
• High self-resonant frequency suitable for RF signal processing
• Robust ceramic core construction for thermal stability

Fixed Inductors Applications

• RF matching networks
• High-frequency filtering circuits
• Impedance matching in wireless communication modules

Fixed Inductors Procurement Notes

Verify the specific suffix 'EHTS' against the manufacturer's latest datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure that the 500 mA current rating aligns with the thermal management requirements of the target circuit design. Cross-reference the RoHS3 compliance status with regional regulatory standards prior to final procurement authorization.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 12 nH is required for high-speed signal paths. The unshielded nature necessitates careful PCB layout to prevent crosstalk with adjacent traces. Compare the 140 mΩ DCR against power loss constraints. Consider the 0402 footprint availability and soldering profile compatibility during the design phase.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series is characterized by small form factors optimized for dense surface-mount assemblies. The HM variant specifically targets applications requiring moderate current handling with precise inductance control in miniature packages.

Fixed Inductors Replacement Considerations

The 0402HP-120EHTS is a related model within the same product family but features different electrical characteristics, including a higher current rating of 1.2 A and lower DC resistance. Verify functional equivalence before substitution.
