0402HP-210EHTS

Fixed Inductors Overview

The 0402HP-210EHTS is a fixed inductor from the Delta Electronics/Components 0402HP series. It features an unshielded drum core, wirewound construction with a ceramic magnetic core. The component has an inductance of 21 nH and a tolerance of ±3%. It supports a rated current of 450 mA and exhibits a DC resistance (DCR) of 46 mΩ. The self-resonant frequency is 1.7 GHz, measured at a test frequency of 250 MHz. It is designed for surface mount installation in a 0402 (1005 Metric) package, with dimensions of 1.15mm x 0.70mm x 0.60mm max height. Operating temperature range is -40°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for high-frequency signal integrity
• Compact 0402 surface mount footprint suitable for dense PCB layouts
• High self-resonant frequency of 1.7 GHz for RF applications

Fixed Inductors Applications

• RF filtering circuits
• Power supply input/output chokes
• Signal line impedance matching

Fixed Inductors Procurement Notes

Verify the specific suffix 'EHTS' against official datasheets to confirm tolerance and packaging details, as variations exist within the 0402HP series. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference manufacturer part numbers with distributor codes to avoid ordering errors due to similar model numbers.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 21 nH is required for high-speed or RF applications. The 450 mA current rating must be sufficient for the target circuit's continuous operation. Consider the unshielded nature of the drum core regarding potential electromagnetic interference coupling in closely spaced components.

Fixed Inductors Part Context

This part belongs to the 0402HP series of fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values in a standard 0402 package, catering to space-constrained electronic designs requiring reliable passive components for power management and signal processing tasks.

Fixed Inductors Replacement Considerations

The 0402HP-210EGTS is a verified substitute within the same series, differing primarily in tolerance specifications. Verify that the alternative's current rating and DCR meet the original design requirements before implementation.
