0402HM-7N0EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HM-7N0EJTS is a fixed wirewound inductor from the 0402HM series, housed in a compact 0402 (1005 Metric) surface-mount package. It features an unshielded drum core design with a nominal inductance of 7 nH and a tolerance of ±0.5 nH. The component supports a rated current of 570 mA and exhibits a DC resistance of 130 mΩ. It achieves a Q value of 25 at 250 MHz and has a self-resonant frequency of 6 GHz. Operating reliably within a temperature range of -55°C to 125°C, it is suitable for high-frequency circuit applications.

Fixed Inductors Feature Summary

• Utilizes a drum core, wirewound construction for stable inductance performance
• Unshielded design minimizes parasitic effects in high-frequency environments
• Capable of handling 570 mA rated current with low DC resistance
• Operates effectively across a wide industrial temperature range

Fixed Inductors Applications

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

Fixed Inductors Procurement Notes

Verify the specific suffix EJTS to confirm the ±0.5 nH tolerance variant, as other suffixes like EDTS or ECTS denote different tolerances. Confirm RoHS3 compliance status during sourcing. Check manufacturer lead times, which may extend up to 24 weeks. Ensure packaging format matches production requirements, such as tape and reel quantities.

Fixed Inductors Selection Notes

Select this component when a precise 7 nH inductance with tight ±0.5 nH tolerance is required for RF applications. The 0402 footprint suits space-constrained designs. Consider the 6 GHz self-resonant frequency limit to ensure operation remains below resonance. Evaluate thermal management needs given the 570 mA current rating and 130 mΩ resistance.

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. The 0402HM-7N0EJTS specifically targets ultra-low inductance applications requiring high precision and stability in compact form factors.

Fixed Inductors Replacement Considerations

Cross-reference with 0402HM-7N0EDTS or 0402HM-7N0ECTS if tolerance differences are acceptable. Verify pinout compatibility and physical dimensions before substitution.
