Overview
The Delevan 108R-104HS is a fixed surface-mount inductor with an inductance of 100 uH and a tolerance of 3%. It features a maximum DC resistance of 31 Ohms and a rated current of 28 mA. The component utilizes a nonstandard package configuration with two leads, constructed for SMD/SMT mounting on printed circuit boards.
Feature Summary
- Fixed inductance value suitable for stable filtering applications
- Surface mount termination style for automated assembly
- Compact physical footprint designed for space-constrained layouts
Applications
- Low-power signal processing circuits
- RF choke applications requiring specific impedance characteristics
- General-purpose power filtering in compact electronic devices
Procurement Notes
Verify the exact lead configuration and package dimensions against the official datasheet before integration, as the nonstandard form factor may require custom footprints. Confirm RoHS compliance status with the manufacturer or authorized distributor, as historical records indicate potential variations in environmental compliance for this obsolete part number.
Selection Notes
Select this component only when the specific 100 uH inductance and 28 mA current rating align precisely with circuit requirements. The high DC resistance necessitates careful thermal management analysis. Ensure the nonstandard package geometry fits within the available board real estate without interfering with adjacent components.
Part Context
This component belongs to the Delevan fixed inductor portfolio, historically utilized in RF and low-power analog applications. As an obsolete part, it represents legacy design technology. Engineers referencing this model should prioritize verification of mechanical fit and electrical parameters due to its discontinued manufacturing status.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status and unique nonstandard package specifications, direct pin-to-pin replacements cannot be verified from public sources. Alternative solutions require custom design validation.
