105R-152K

Overview

The Delevan 105R-152K is a surface-mount RF inductor with an inductance of 1.5 µH and a tolerance of ±10%. It features a maximum DC current rating of 280 mA and a maximum DC resistance of 1.2 Ohms. The component utilizes an unshielded wirewound core design suitable for high-frequency applications.

Feature Summary

• Unshielded wirewound construction for RF signal handling
• Surface mount package for automated PCB assembly
• Fixed inductance value for stable circuit performance

Applications

• RF filtering circuits
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan and other entities may list this part. Confirm lifecycle status and RoHS compliance against the latest official datasheet before integration. Ensure the unshielded variant matches the schematic requirements to prevent unexpected coupling issues.

Selection Notes

Select this component when a 1.5 µH unshielded SMD inductor is required. Verify that the 280 mA current limit meets the circuit's peak demands. Consider the lack of shielding if electromagnetic interference is a concern in the layout.

Part Context

This part belongs to the fixed inductor category within the Delevan portfolio. It serves as a passive component for radio frequency applications, distinct from power chokes or shielded variants found in other series.

Replacement Considerations

Direct substitutes include parts with identical 1.5 µH inductance, 280 mA current rating, and 1.2 Ohm DCR in an unshielded SMD form factor. Cross-reference pinout and thermal characteristics for compatibility.
