Fixed Inductors Procurement Notes
Verify the specific ordering suffix to confirm tolerance designation, as variations may exist within the product line. Ensure that the selected component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the datasheet specifications against your circuit's thermal and current constraints before finalizing procurement decisions.
Fixed Inductors Selection Notes
Select this component for applications requiring a compact shielded inductor capable of handling up to 2.8 A. Consider the 195 mΩ DC resistance for efficiency calculations in low-voltage power paths. The wide operating temperature range supports use in demanding industrial environments where thermal stability is critical for consistent performance.
Fixed Inductors Part Context
This part belongs to the CTMMP series of fixed inductors from Central Technologies. The series offers various inductance values tailored for power electronics. The CTMMP1805F-4R7M specifically targets mid-range current applications in space-constrained designs, providing a balance between electrical performance and physical footprint compared to larger unshielded alternatives.
Fixed Inductors Replacement Considerations
Direct substitutes must match the 4.7 µH value, 2.8 A current rating, and SMD form factor. Verify that alternative components offer comparable shielding effectiveness and operate within the same -55°C to +125°C temperature range to ensure system reliability.
