Fixed Inductors Procurement Notes

This component is officially designated as obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement must rely on remaining stock from authorized distributors or secondary markets. Verify the authenticity of available units and check for potential supply chain disruptions due to the End-of-Life status. Ensure that any replacement strategy accounts for the discontinuation date of June 1, 2020, to avoid future production shortages.

Fixed Inductors Selection Notes

Engineers should prioritize this part only if existing designs are validated for its specific electrical characteristics and physical dimensions. Due to its discontinued status, alternative sourcing requires careful evaluation of long-term availability. Consider the tight tolerance and current rating when designing for sensitive RF applications. Validate that the 0201 footprint aligns with the target PCB layout constraints before proceeding with integration or substitution planning.

Fixed Inductors Part Context

The CIH03T8N2JNC belongs to the CIH03 series of chip inductors from Samsung Electro-Mechanics. This series focuses on providing stable inductance values in ultra-compact packages suitable for modern portable electronics. As a passive component, it plays a critical role in managing signal flow and noise suppression in high-density circuit boards where space is limited.

Fixed Inductors Replacement Considerations
