• Unshielded vertical cylinder design for flexible circuit integration.
• UL sleeved leads to enhance safety and insulation reliability.
• Radial pin configuration suitable for through-hole mounting.

Fixed Inductors Applications

• Noise filtering choke coils in electronic circuits.
• Peaking coil applications in signal processing.
• General-purpose inductive components in power supplies.

Fixed Inductors Procurement Notes

Verify the specific suffix '470K' corresponds to the required 47 µH inductance value during procurement. Confirm that the ±10% tolerance aligns with the target circuit design specifications. Ensure the 3.5 A current rating meets the operational requirements of the application environment. Check for any specific packaging or reel requirements if applicable.

Fixed Inductors Selection Notes

Select this component when a radial, unshielded inductor with high current handling capability is required. The 47 µH value is suitable for specific frequency filtering or peaking needs. Consider the 11.00 mm diameter for PCB space constraints. Verify thermal performance at the expected operating temperature range relative to the current load.

Fixed Inductors Part Context

This part belongs to the CTRFB1010F series of peaking coils manufactured by Central Technologies. The series offers a wide range of inductance values, typically from 12 µH to 18,000 µH, all available in a ±10% tolerance. These components are characterized by their radial leaded format and unshielded construction, making them distinct from shielded surface-mount alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include other CTRFB1010F variants with different inductance values, such as CTRFB1010F-331K or CTRFB1010F-560K, provided the inductance difference is acceptable for the circuit function. Cross-brand replacements require matching the 47 µH inductance, 3.5 A current rating, and radial package dimensions.
