CTH8F-122K

Fixed Inductors Overview

The CTH8F-122K is a fixed axial leaded inductor manufactured by Central Technologies. It features a nominal inductance of 1.2 mH with a tolerance of ±10%. The component has a maximum DC resistance of 1.04 Ω and supports a continuous current rating of 600 mA, with a saturation current (Isat) of 790 mA. It operates within a temperature range of -55 °C to 125 °C. The device is unshielded, RoHS compliant, and utilizes a tubular package design.

Fixed Inductors Feature Summary

• Unshielded wirewound construction for general power applications
• Axial leaded termination for through-hole mounting
• Compliant with environmental standards including RoHS

Fixed Inductors Applications

• Power line chokes
• General purpose filtering circuits
• Wireless charging coil assemblies

Fixed Inductors Procurement Notes

Verify the specific suffix 'K' corresponds to the required ±10% tolerance when sourcing. Confirm that the 1.04 Ω maximum DC resistance and 600 mA continuous current ratings align with the target circuit's thermal and electrical requirements. Ensure the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.

Fixed Inductors Selection Notes

Select this component for applications requiring moderate inductance values in through-hole designs. The 1.2 mH value suits low-frequency filtering or energy storage roles. Consider the 790 mA saturation limit to prevent performance degradation under peak load conditions. The axial form factor facilitates easy integration into standard PCB layouts without specialized surface-mount equipment.

Fixed Inductors Part Context

This part belongs to the CTH8F series of fixed inductors from Central Technologies. The series offers various inductance options, such as the 270 µH CTH8F-271K variant. These components are designed for robustness in general-purpose electronic systems, providing reliable inductive properties across a wide operating temperature range.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 1.2 mH nominal inductance, ±10% tolerance, axial package, and similar current ratings. Verify that alternative manufacturers offer comparable DC resistance and saturation current specifications to ensure circuit compatibility.
