0402HM-270EJTS

Fixed Inductors Overview

The 0402HM-270EJTS is a fixed inductor from Delta Electronics/Components, featuring a 27 nH nominal inductance with ±5% tolerance. It utilizes an unshielded drum core wirewound construction on a ceramic material. The component supports a rated current of 280 mA and exhibits a DC resistance (DCR) of 520 mOhm. Designed for surface mount installation, it operates within a temperature range of -40°C to 125°C. The physical dimensions are 1.15mm x 0.70mm x 0.60mm max, conforming to the 0402 (1005 Metric) package standard.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for minimal magnetic interference
• Ceramic core material supporting high-temperature operation up to 125°C
• Compact 0402 surface mount footprint for dense PCB layouts

Fixed Inductors Applications

• RF signal filtering in compact wireless modules
• Power supply input/output filtering for low-current circuits
• Impedance matching networks in RF front-end stages

Fixed Inductors Procurement Notes

Verify the specific suffix 'EJTS' against manufacturer documentation to confirm lead-free status and RoHS3 compliance. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the full part number with official Delta Electronics databases to validate current production status and availability before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a small 0402 footprint is required for 27 nH applications. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with nearby traces. Verify that the 280 mA current rating meets the circuit's operational demands and that the 520 mOhm DCR is acceptable for the application's power loss constraints.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values in a standardized 0402 package size. The HM designation typically indicates specific performance characteristics such as the drum core construction and unshielded nature, distinguishing it from other series like HP or CT which may offer different shielding or tolerance specifications.

Fixed Inductors Replacement Considerations

The 0402HM-270EGTS is listed as a similar alternative by the manufacturer. Verify if the EGTS suffix denotes any functional differences regarding tolerance or packaging compared to the EJTS variant. Other manufacturers offering 0402 27nH inductors require careful comparison of DCR, current rating, and self-resonant frequency to ensure compatibility.
