0402HM-1N5EKTS

Fixed Inductors Overview

The 0402HM-1N5EKTS is a fixed surface-mount inductor from Delta Electronics, featuring a 1.5 nH nominal inductance with ±10% tolerance. It utilizes an unshielded drum core wirewound design on a ceramic substrate, housed in a compact 0402 (1005 Metric) package measuring 1.15mm x 0.70mm x 0.60mm max. The component supports a rated current of 1 A and exhibits a low DC resistance of 30 mΩ. It offers a Q value of 10 at 250 MHz and achieves a self-resonant frequency of 18 GHz, operating reliably within a temperature range of -55°C to 125°C.

• Unshielded drum core wirewound construction for minimal parasitic effects
• High-frequency performance with 18 GHz self-resonant frequency
• Compact 0402 footprint suitable for dense surface-mount layouts
• Ceramic core material ensuring stable thermal characteristics

Fixed Inductors Applications

• RF matching networks in wireless communication modules
• Impedance matching circuits in high-speed digital interfaces
• Power filtering stages in portable electronic devices
• Signal conditioning in IoT sensor nodes

Fixed Inductors Procurement Notes

Verify the complete part number including the suffix 'K' which denotes the specific tolerance class. Confirm that the required packaging format aligns with production needs, as options include tape-and-reel, cut tape, or Digi-Reel. Ensure the procurement channel provides traceability documentation consistent with RoHS3 compliance requirements for environmental regulations.

Fixed Inductors Selection Notes

Select this component when circuit design demands ultra-low inductance values below 2 nH for high-frequency signal integrity. The unshielded nature requires careful PCB layout consideration to minimize electromagnetic interference coupling with adjacent traces. Verify that the 1 A current rating exceeds the peak operational current of the target application to prevent saturation.

Fixed Inductors Part Context

This part belongs to the 0402HM series of high-frequency inductors designed by Delta Electronics. The series focuses on providing stable inductance values in miniature packages for RF and microwave applications. The 0402HM-1N5EKTS represents the lowest inductance variant in the standard lineup, optimized for GHz-range operations where parasitic capacitance must be strictly controlled.

Fixed Inductors Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Equivalent components must match the 1.5 nH value, 0402 package dimensions, and 1 A current rating. Verify that alternative manufacturers offer comparable self-resonant frequencies and Q factors to maintain circuit performance.
