0402HM-300EKTS

Fixed Inductors Overview

The 0402HM-300EKTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a drum core wirewound design with an unshielded construction. It offers an inductance of 30 nH with a ±10% tolerance and a rated current of 270 mA. The component exhibits a DC resistance of 580 mOhm and operates within a temperature range of -55°C to 125°C. Key electrical characteristics include a Q value of 25 at 250 MHz and a self-resonant frequency of 4 GHz. Measured in a compact 0402 (1005 metric) package, it utilizes a ceramic core material for stable performance.

• High-frequency decoupling in compact electronic circuits

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations may exist between tape-and-reel and cut-tape formats. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders to avoid handling issues.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 30 nH is required in a minimal footprint. Ensure the circuit current does not exceed the 270 mA rating to prevent saturation or overheating. Consider the unshielded nature of the device regarding nearby sensitive components or trace routing to mitigate potential electromagnetic interference effects.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors manufactured by Delta Electronics/Components. The series focuses on small-form-factor solutions for modern electronics requiring precise inductance values in restricted board spaces. These components are designed for automated surface-mount assembly processes.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 30 nH inductance, 0402 package dimensions, and similar current ratings. Verify that alternative parts maintain comparable self-resonant frequencies and Q factors for RF applications. Cross-reference manufacturer datasheets to confirm pinout compatibility and thermal characteristics.
