• RF inductor circuits
• General purpose filtering applications
• Power supply output chokes

Fixed Inductors Procurement Notes

Verify that the specific part number suffix matches the required tolerance grade, as ordering specifications require explicit tolerance codes. Confirm compliance requirements against project standards, noting this variant is RoHS compliant unlike some non-F series counterparts. Ensure thermal management accounts for the 125 °C maximum operating temperature limit during integration.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 3300 µH is required in an axial form factor. Consider the low current rating of 40 mA and high DC resistance of 53 Ω for circuit design constraints. The shielded design makes it suitable for noise-sensitive environments where unshielded alternatives might cause interference.

Fixed Inductors Part Context

This component belongs to the CTS3F series of general purpose inductors manufactured by Central Technologies. The series offers various inductance values ranging from microhenries to millihenries in a consistent axial tubular package. The 'F' suffix typically denotes RoHS compliance and specific material characteristics distinct from the standard CTS3 or CTS2 series.

Fixed Inductors Replacement Considerations

Direct substitutes include other CTS3F series variants with identical physical dimensions but different inductance values if electrical parameters allow adjustment. Cross-series replacement with CTS3 or CTS2 models requires verification of lead compatibility and tolerance grades, noting potential differences in RoHS status and shielding effectiveness.
