Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'SNC' against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with standard SMT reflow profiles. Confirm availability status as inventory levels fluctuate. Check for any recent product change notifications or end-of-life announcements prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when ultra-low inductance values near 1 nH are required for high-frequency circuit tuning. The unshielded design minimizes parasitic effects but requires careful layout to prevent magnetic interference. Consider the 490 mA current rating for power handling requirements. The 0201 package size dictates board space constraints. Verify that the 10 GHz self-resonant frequency aligns with the target operational bandwidth.

Fixed Inductors Part Context

This part belongs to the CIH series of chip inductors from Samsung Electro-Mechanics. These components are designed for general electronic circuits requiring precise inductance values. The series offers various inductance options within the 0201 package format. They are commonly used in consumer electronics and communication devices where small form factors are critical.

Fixed Inductors Replacement Considerations

Check for direct substitutes with identical 1 nH inductance and 0201 footprint. Verify equivalent DCR and current ratings. Ensure the replacement maintains the same unshielded characteristic and frequency response. Consult the manufacturer's cross-reference list for approved alternatives.
