• General purpose filtering
• Power supply applications

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates ±5% inductance tolerance against the official datasheet. Confirm RoHS compliance status and conformal coating requirements match the target application environment. Ensure axial lead dimensions are compatible with the PCB layout.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor with high-temperature stability is required. Compare DCR and rated current specifications against circuit load requirements. Consider the operating temperature range and physical size constraints relative to alternative series like CTS2F or CTCDRH73.

Fixed Inductors Part Context

This part belongs to the CTC3F series of conformal-coated axial inductors from Central Technologies. It shares the general shielding and coating characteristics with other members of the family but differs in inductance value and electrical ratings based on its specific model designation.

Fixed Inductors Replacement Considerations

Direct substitutes include CTC3F-331K (±10% tolerance) or CTS2F-331J (uncoated). Verify that the replacement maintains the same axial package style and meets the original thermal and current requirements.
