0402HS-400EKTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HS-400EKTS is a fixed surface-mount inductor with an inductance of 40 nH and a tolerance of ±10%. It features a drum core, wound construction using ceramic material and operates without shielding. The component has a DC resistance (DCR) of 500 mOhm and a rated current of 320 mA. It exhibits a Q value of 25 at 250 MHz and a self-resonant frequency of 2.24 GHz. Measured at 100 MHz, it fits the 0402 (1005 metric) package with dimensions of 1.00mm x 0.50mm x 0.60mm max height. Operating temperature ranges from -55°C to +125°C.

Fixed Inductors Feature Summary

• Utilizes a drum core, wound structure with ceramic magnetic material for stable performance.
• Provides high self-resonant frequency characteristics suitable for RF applications.
• Features a compact 0402 footprint designed for dense surface-mount assembly.

Fixed Inductors Applications

• RF signal filtering in communication modules
• Impedance matching networks in wireless devices
• Power supply input/output filtering

Fixed Inductors Procurement Notes

Verify the specific suffix 'EKTS' against manufacturer documentation to confirm packaging type and tape/reel specifications. Ensure the requested quantity aligns with standard reel sizes. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the full part number to distinguish from similar variants like 0402HM or 0402HS series with different tolerances or current ratings.

Fixed Inductors Selection Notes

Select this component when a low-inductance value of 40 nH is required in a minimal 0402 footprint. Consider the 320 mA current rating and 500 mOhm DCR for power handling needs. The non-shielded design may require layout considerations for EMI. Verify that the 2.24 GHz self-resonant frequency meets the operational bandwidth requirements of the target circuit.

Fixed Inductors Part Context

This part belongs to the Delta Electronics 0402HS series of fixed inductors. The series offers various inductance values within the 0402 package size. The HS designation typically indicates specific electrical characteristics distinct from the HM or HT series. These components are manufactured for high-frequency electronic applications requiring small form factors.

Fixed Inductors Replacement Considerations

Direct substitutes include the 0402HS-400EJTS, which shares identical electrical parameters but may differ in packaging configuration. Other Delta 0402HS series parts with 40 nH inductance should be verified for matching current ratings and DCR values before substitution.
