CTRFB1010F-222K

Fixed Inductors Overview

The CTRFB1010F-222K is a fixed radial inductor manufactured by Central Technologies, featuring an inductance of 2.2 mH (2200 µH). It operates with a maximum DC current rating of 500 mA and exhibits a maximum DC resistance of 4.1 Ohms. The component utilizes a vertical cylinder package design with radial terminals for through-hole mounting. It is available exclusively in ±10% tolerance and is classified as an unshielded general-purpose peaking coil.

Fixed Inductors Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm the exact inductance value and tolerance class. Ensure that the required operating current does not exceed the 500 mA maximum rating to prevent thermal issues. Confirm that the unshielded nature of the component aligns with the electromagnetic interference requirements of the target application environment.

Fixed Inductors Selection Notes

Select this component when a 2.2 mH inductance value is required within a radial vertical form factor. Consider the 4.1 Ohm DC resistance limit for voltage drop calculations in the circuit design. The ±10% tolerance specification should be evaluated against the precision requirements of the signal processing or power management stage where the inductor will be integrated.

Fixed Inductors Part Context

This component belongs to the CTRFB1010F series of peaking coils produced by Central Technologies. The series offers a range of inductance values from 12 µH to 18,000 µH, all sharing similar radial vertical packaging characteristics. The product line is designed for general-purpose electronic applications requiring reliable passive inductive components.

Fixed Inductors Replacement Considerations

Compatible substitutes include other parts from the CTRFB1010F series with matching 2.2 mH specifications, such as variants with different tolerance codes if available. Cross-reference with other manufacturers offering radial unshielded inductors with equivalent 2.2 mH inductance, 500 mA current rating, and ≤4.1 Ohm DC resistance.
