108R-104J

Overview

The Delevan 108R-104J is a fixed surface-mount inductor with an inductance of 100 µH and a tolerance of ±5%. It features a maximum DC resistance of 31 Ohms and a rated current of 28 mA. The component utilizes an unshielded design with nonstandard two-lead termination for PCB mounting.

Feature Summary

• Unshielded construction to minimize magnetic interference coupling
• Fixed inductance value suitable for stable filtering applications
• Surface-mount package optimized for automated assembly processes

Applications

• Power supply input filtering
• Signal line noise suppression
• General-purpose electronic circuit blocking

Procurement Notes

Verify the specific manufacturer source, as API Delevan components are often distributed by third-party suppliers. Confirm RoHS compliance status and lead-free availability directly with the vendor before ordering. Ensure the nonstandard lead configuration matches your PCB footprint requirements.

Selection Notes

Select this component when a high-impedance path is required at specific frequencies. The low current rating necessitates careful thermal management in power-sensitive designs. Verify that the unshielded nature does not interfere with nearby sensitive traces or components.

Part Context

This part belongs to the 108R series of fixed inductors from Delevan. It shares the 100 µH nominal value with other variants but differs in tolerance and physical dimensions. It serves as a passive component for impedance matching and noise reduction.

Replacement Considerations

Direct substitutes include the 108R-104K (±10% tolerance) and 108R-104H (±3% tolerance). Cross-reference the 1812R-104J for shielded alternatives, though electrical characteristics may vary significantly.
