4470R-32G

Fixed Inductors Overview

The Delevan 4470R-32G is a fixed axial leaded RF inductor featuring an unshielded molded construction. It provides a nominal inductance of 390 µH with a tight tolerance of ±2%. The component has a maximum DC resistance of 15.5 Ohms and a current rating of 180 mA. Designed for through-hole mounting, it serves as a specialized passive element for radio frequency circuit applications requiring stable inductive characteristics.

Fixed Inductors Feature Summary

• Unshielded molded design for specific RF interference management
• Axial leaded configuration for reliable through-hole PCB integration
• High precision ±2% inductance tolerance for critical signal integrity

Fixed Inductors Applications

• Radio frequency filtering circuits
• Impedance matching networks
• RF choke applications in communication equipment

Fixed Inductors Procurement Notes

Verify the exact suffix code against manufacturer documentation to confirm tolerance and electrical specifications. Ensure the unshielded variant matches the electromagnetic compatibility requirements of the target assembly. Confirm axial lead dimensions fit the designated PCB footprint before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when high inductance stability is required in a compact axial form factor. The unshielded nature necessitates careful layout planning to minimize external magnetic coupling. Verify that the 180 mA current rating exceeds the maximum operating current of the application to prevent saturation or thermal issues.

Fixed Inductors Part Context

This part belongs to the Delevan 4470R series of fixed RF inductors. The series offers various inductance values and tolerances in an axial package. It is distinct from shielded SMD variants like the 4379R series, providing a traditional through-hole solution for legacy or specific RF designs.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 390 µH value, ±2% tolerance, and 15.5 Ohm DCR. Verify physical axial dimensions for board compatibility. Cross-reference API Delevan datasheets for equivalent series parts with similar electrical profiles.
