Fixed Inductors Procurement Notes
This component is officially discontinued by the manufacturer. Inventory availability is limited to existing stock only; no new production will occur once current supplies are exhausted. Verify end-of-life status before finalizing designs. Sourcing should focus on authorized distributors holding remaining quantities, as future procurement cannot be guaranteed.
Fixed Inductors Selection Notes
Select this part for applications requiring ultra-low inductance values in minimal space. Ensure the operating environment stays within the specified temperature range. Consider the low rated current when designing power paths. Due to its discontinuation, verify long-term supply chain viability or identify approved substitutes early in the development cycle.
Fixed Inductors Part Context
Part of the CIH03Q series, designed for high-frequency performance. Manufactured by Samsung Electro-Mechanics, a provider of passive components. The 0201 case size supports miniaturization trends in modern electronics. This specific model represents a standard unshielded inductor option for RF and high-speed data lines.
Fixed Inductors Replacement Considerations
Public confirmed substitutes include LRC0201BS3N3GV001T by Johanson Technology Inc. and MLG0603S3N3ST000 by TDK. Both are direct replacements with identical electrical specifications. Verify pin compatibility and thermal characteristics during integration.
