Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required tolerance and packaging configuration. Confirm that the axial lead length and diameter meet the target PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the manufacturer part number with official distributor catalogs to confirm current product status and availability.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor with low DC resistance is required for general-purpose or RF applications. Consider the 251 mA current rating and 220 µH inductance value against circuit design specifications. Evaluate the physical footprint constraints relative to the 4.06 mm diameter and 11.4 mm length dimensions. Verify compatibility with automated insertion equipment if high-volume production is planned.

Fixed Inductors Part Context

This component belongs to the CTS4F series of shielded mold axial inductors from Central Technologies. The series offers various inductance values with consistent physical dimensions and shielding characteristics. These inductors are designed for applications requiring reduced magnetic field leakage compared to unshielded alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 220 µH inductance, ±5% tolerance, and 251 mA current rating. Verify identical axial package dimensions (4.06 mm x 11.4 mm) and lead diameter (0.51 mm). Ensure the replacement part also features shielded construction and amorphous core material to maintain equivalent EMI performance.
