105R-271H

Overview

The Delevan 105R-271H is a fixed surface-mount RF inductor with a nominal inductance of 270 nH and a tolerance of ±3%. It features a maximum DC resistance of 230 mΩ and a current rating of 650 mA. The component utilizes an unshielded chip construction designed for high-frequency applications.

Feature Summary

• Unshielded SMT design suitable for RF circuits
• High Q-factor performance at operating frequencies
• Compact footprint for space-constrained layouts

Applications

• RF matching networks
• Filter circuits
• Impedance transformation stages

Procurement Notes

Verify RoHS compliance status as datasheets may vary by production batch. Confirm lead-free solderability requirements against specific manufacturing standards. Ensure ESD handling protocols are followed during assembly to prevent damage to the sensitive magnetic core structure.

Selection Notes

Select this component for low-inductance RF applications requiring precise tolerance. Evaluate thermal management needs given the 650 mA current limit. Compare physical dimensions against PCB silkscreen constraints to ensure proper placement and spacing relative to adjacent components.

Part Context

This part belongs to the API Delevan 105 series of general-purpose fixed inductors. It shares the same form factor and mounting style as other variants in the family, differing primarily in inductance value and associated electrical parameters such as DCR and saturation current.

Replacement Considerations

Direct substitutes include the 105R-271HS variant, which offers identical electrical specifications but with RoHS-compliant plating. Cross-reference pinout and inductance values when considering alternative manufacturers' surface-mount RF inductors.
