0603HP-4N3EKTS

Fixed Inductors Overview

The Delta Electronics/Components 0603HP-4N3EKTS is a fixed surface-mount inductor with an inductance of 4.3 nH and a tolerance of ±10%. It features a drum core, wirewound construction using ceramic material. The component has a maximum DC resistance of 80 mOhm and a rated current of 1.3 A. It operates within a temperature range of -55°C to 125°C. The package size is 0603 (1608 metric), measuring 1.60 mm in length, 0.80 mm in width, and 0.80 mm in height.

Fixed Inductors Feature Summary

• Drum core wirewound design for high-frequency stability
• Unshielded configuration suitable for compact layouts
• Ceramic core material ensuring thermal resilience

Fixed Inductors Applications

• RF matching networks
• High-speed digital signal filtering
• Power supply input/output chokes

Fixed Inductors Procurement Notes

Verify the specific suffix 'K' indicates the standard tolerance and packaging format upon ordering. Confirm that the 0603 footprint dimensions align with your PCB silkscreen and copper pad design. Ensure the 1.3A current rating meets the peak load requirements of your circuit to prevent saturation or excessive heating during operation.

Fixed Inductors Selection Notes

Select this component when a very low inductance value near 4.3 nH is required for RF applications. Compare against the 0603CS series if lower current handling is acceptable, or the 0402HP series if space constraints are tighter. Verify that the unshielded nature does not cause EMI issues in dense layouts.

Fixed Inductors Part Context

This part belongs to the 0603HP series of high-performance fixed inductors from Delta Electronics. The series focuses on ultra-low inductance values for high-frequency circuits. The HP designation typically implies higher current handling capabilities compared to standard variants in the same package size.

Fixed Inductors Replacement Considerations

Direct substitutes include the 0603CS-4N3EKTS and 0603HP-4N7ECTS. Note that the CS variant has different electrical characteristics. Always verify pin compatibility and thermal performance before swapping.
