0402HP-120EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HP-120EJTS is a fixed surface-mount inductor with a nominal inductance of 12 nH and a tolerance of ±5%. It features an unshielded drum core wirewound construction using a ceramic magnetic core. The component supports a rated current of 1.2 A and exhibits a DC resistance of 90 mΩ. Its self-resonant frequency reaches 4.4 GHz at a test frequency of 250 MHz. Housed in a compact 0402 (1005 Metric) package measuring 1.15 mm x 0.70 mm x 0.60 mm, it operates within a temperature range of -40°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for high-frequency signal integrity
• Compact 0402 footprint optimized for dense surface-mount layouts
• High self-resonant frequency capability up to 4.4 GHz
• Robust thermal performance across extended industrial temperature ranges

Fixed Inductors Applications

• DC-DC converter input/output filtering circuits
• Signal conditioning stages in high-speed data interfaces
• Power distribution network decoupling applications

Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'EJTS' to confirm the ±5% tolerance variant, as other suffixes like 'EKTS' or 'EHTS' indicate different tolerances. Confirm RoHS3 compliance status and MSL level 1 classification during sourcing. Ensure the procurement channel provides valid traceability documentation consistent with manufacturer standards.

Fixed Inductors Selection Notes

Select this component when a precise 12 nH value with tight ±5% tolerance is required for RF or power filtering. The 1.2 A current rating suits moderate power applications, while the 90 mΩ DCR minimizes conduction losses. Consider the 0402 package size constraints and the unshielded nature for potential EMI sensitivity in sensitive circuit designs.

Fixed Inductors Part Context

This part belongs to the 0402HP series of high-performance fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores and wirewound technology to achieve high Q-factors and stable inductance values in miniature packages. It is designed for demanding electronic applications requiring reliable passive components in space-constrained environments.

Fixed Inductors Replacement Considerations

Direct substitutes include 0402HP-120EKTS and 0402HP-120EHTS, which share identical electrical parameters but differ in tolerance specifications. Verify that any replacement maintains the same 0402 footprint and thermal characteristics to ensure mechanical compatibility.
