Fixed Inductors Procurement Notes

Verify the specific suffix 'SNE' against official Samsung Electro-Mechanics documentation to confirm packaging type and tape/reel specifications. Ensure that the requested quantity aligns with standard manufacturing pack sizes to avoid handling discrepancies. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when designing power supplies requiring a balance between high current handling and low profile height. The 1.4A rated current and 2.2A saturation current make it suitable for moderate power applications where space is constrained. Consider the 150 mΩ DCR for efficiency calculations and ensure the operating environment stays within the specified -40°C to +125°C range for optimal longevity.

Fixed Inductors Part Context

This inductor belongs to the CIGW series of metal composite power inductors manufactured by Samsung Electro-Mechanics. The series is engineered for high-frequency switching applications, offering superior shielding compared to unshielded alternatives. The 1008 package size represents a standard industry form factor, facilitating integration into various consumer and industrial electronic designs without requiring significant layout modifications.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 µH inductance, 1008 package dimensions, and similar current ratings. Verify compatibility with existing thermal constraints and magnetic shielding requirements. Consult official cross-reference lists or manufacturer guidelines for approved alternative part numbers to ensure electrical and mechanical equivalence.
