105R-103F

Overview

The Delevan 105R-103F is a fixed surface-mount inductor with an inductance of 10 µH and a tolerance of ±1%. It features a maximum DC resistance of 5.6 Ohms and a rated current of 130 mA. The component utilizes an unshielded wirewound design on a ferrite core, housed in a nonstandard package with two leads. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded wirewound construction for specific RF applications
• Ferrite core material supporting high-frequency stability
• Compact surface-mount form factor with standard terminal configuration

Applications

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

Procurement Notes

Verify the exact physical dimensions against the official datasheet due to the nonstandard package designation. Confirm RoHS compliance status through the manufacturer's documentation before integration. Ensure the 130 mA current rating aligns with the circuit's operational requirements to prevent saturation or thermal issues during deployment.

Selection Notes

Select this component when a compact, unshielded 10 µH inductor is required for RF environments. The low current rating suits signal-level applications rather than power handling. Compare physical footprint constraints against alternative SMD packages if space is limited. Validate thermal performance at the upper operating limit of 125°C.

Part Context

This part belongs to the Delevan fixed inductor portfolio, specifically designed for radio frequency and general electronic applications. It represents a legacy component type often found in established communication hardware designs requiring stable inductance values in small footprints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify mechanical compatibility and electrical equivalence with any potential cross-reference components before substitution.
