CTC2F-4R7J

Fixed Inductors Overview

The CTC2F-4R7J is a general purpose inductor manufactured by Central Technologies. It features an axial leaded package with conformal coating and contains one element. The nominal inductance is 470 nH (0.47 µH) with a tolerance of 5%. The component has a maximum DC resistance of 170 mΩ and operates within a temperature range of -55 °C to 125 °C. It is RoHS compliant and lead-free.

Fixed Inductors Feature Summary

• Axial leaded construction with conformal coating for environmental protection
• Amorphous magnetic core material for general purpose applications
• RoHS compliant and lead-free manufacturing

Fixed Inductors Applications

• RF circuits
• General purpose filtering
• Signal processing

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates the 5% tolerance level as documented in official Central Technologies datasheets. Confirm that the axial lead length and diameter meet your PCB layout requirements, as these physical dimensions are critical for through-hole mounting. Ensure the operating temperature range of -55 °C to 125 °C aligns with your system's thermal environment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 0.47 µH is required for RF or signal integrity applications. The axial form factor is suitable for manual assembly or wave soldering processes where surface mount devices are not preferred. Consider the 170 mΩ DC resistance for current handling capabilities in low-power signal paths rather than high-current power supply lines.

Fixed Inductors Part Context

This part belongs to the CTC2F series from Central Technologies, which offers a range of fixed inductors from 0.022 µH to 1,000 µH. The series is characterized by its cylindrical shape and amorphous magnetic core. The CTC2F-4R7J represents a specific low-inductance variant within this broader family, designed for applications requiring precise small-value inductance.

Fixed Inductors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed using key parameters: 0.47 µH inductance, 5% tolerance, axial package, and similar DC resistance values.
