Procurement Notes
Verify availability status as this component may be subject to obsolescence or limited supply. Confirm RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Ensure that the radial lead configuration matches your PCB layout requirements and that the 140 mΩ DCR meets your circuit's power loss constraints.
Selection Notes
Select this component when a low-inductance, unshielded solution is required for general-purpose applications. The radial lead form factor is ideal for manual assembly or specific through-hole designs where SMD components are not preferred. Consider the 830 mA current rating to ensure adequate headroom for your application's peak currents.
Part Context
This part belongs to the family of fixed inductors manufactured by API Delevan Inc. It is categorized under passive components, specifically inductors and coils. The 105-121K model represents a standard value in their unshielded radial leaded series, often used in older or specialized electronic designs requiring robust, simple inductive elements.
Replacement Considerations
