CTRLB9012F-100K

Fixed Inductors Overview

The CTRLB9012F-100K is a high-current power toroidal inductor manufactured by Central Technologies. It features a radial leaded through-hole mounting configuration suitable for standard PCB assembly processes. The component provides an inductance of 10 µH with a tolerance of ±10%, indicated by the 'K' suffix. Designed for robust performance, it supports a maximum rated current of 3.4 mA and exhibits a DC resistance of 0.093 Ω. The device operates within a temperature range of -55 °C to 125 °C and complies with RoHS standards.

Fixed Inductors Feature Summary

• High-current power toroid construction
• Radial axial leaded package
• RoHS compliant manufacturing

Fixed Inductors Applications

• General purpose inductive filtering
• RF circuit applications
• Power supply input/output stages

Fixed Inductors Procurement Notes

Verify the specific tolerance code required for the application design, as the K suffix denotes ±10% inductance variation. Confirm that the 3.4 mA maximum rated current aligns with the peak and RMS current requirements of the target circuit to prevent saturation or thermal issues. Ensure the radial lead spacing matches the PCB footprint specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact toroidal inductor with radial leads is required for general-purpose or RF applications. Consider the low maximum current rating of 3.4 mA carefully; it is suitable for signal conditioning or low-power stages rather than high-current power delivery. Compare against other series like CTC5F if higher current capacity or different form factors are needed.

Fixed Inductors Part Context

This part belongs to the High Current Power Toroids family from Central Technologies, which offers various inductance values and tolerance options. The CTRLB9012F series specifically utilizes a tubular package design optimized for through-hole mounting. It serves as a passive component alternative for designs requiring reliable inductance in constrained spatial environments.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts within the Central Technologies CT94F or CTC5F series that match the 10 µH inductance and ±10% tolerance. Verify that any replacement maintains the same radial lead configuration and meets the -55 °C to 125 °C operating temperature range.
