CTRFB0810F-101K

Fixed Inductors Overview

The CTRFB0810F-101K is a fixed wirewound inductor from Central Technologies, designed for through-hole mounting. It features an unshielded radial vertical cylinder package with dimensions of 9.5 x 11.5 x 5 mm. The component provides an inductance of 100 µH with a tolerance of ±10%. It operates at a test frequency of 100 kHz and supports a maximum DC resistance (DCR) of 200 mΩ. The current rating is specified at 1.8 A, while the saturation current (Isat) is rated at 1.4 A.

Fixed Inductors Feature Summary

• Unshielded wirewound construction for general-purpose applications
• Radial through-hole lead configuration for vertical PCB mounting
• High current handling capability with defined saturation limits

Fixed Inductors Applications

• Power supply filtering circuits
• Signal peaking coils
• General electronic circuit inductive components

Fixed Inductors Procurement Notes

Verify the specific current ratings against application requirements, noting the distinction between rated current and saturation current. Confirm that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field emission. Ensure the radial lead spacing matches the target PCB footprint before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when a 100 µH inductance value is required with a radial form factor. Consider the 1.4 A saturation limit for peak load conditions rather than just the continuous current rating. The unshielded nature makes it suitable for layouts where magnetic interference can be managed or is negligible compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the CTRFB0810F series of fixed inductors manufactured by Central Technologies. The series offers various inductance values, such as 10 µH and 3.3 mH variants, sharing similar physical dimensions and mounting styles. This specific model represents the 100 µH option within that product line.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 100 µH inductance, radial through-hole package, and comparable current ratings. Verify DCR and saturation current specifications to ensure equivalent performance in the target circuit without modifying the PCB layout.
