4470-48J

Fixed Inductors Overview

The Delevan 4470-48J is a fixed axial leaded molded unshielded RF inductor with an inductance of 8.2 mH and a tolerance of ±3%. It features a maximum DC resistance of 75 Ohms and a rated current of 82 mA. The component exhibits a minimum Q factor of 65 at 250 kHz and a self-resonant frequency of 520 kHz. Designed for PCB mounting, it operates within a temperature range of -55°C to 125°C.

Fixed Inductors Feature Summary

• Molded unshielded construction for consistent performance
• Axial leaded termination style for through-hole mounting
• Iron-core design supporting high inductance values

Fixed Inductors Applications

• RF circuit filtering
• General purpose inductive applications
• Signal processing circuits

Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package quantity and reel specifications during ordering. Ensure the ±3% tolerance aligns with circuit requirements. Check lead time availability as stock levels vary by distributor.

Fixed Inductors Selection Notes

Select this component when an 8.2 mH inductance with low current handling (82 mA) is required. The 75 Ohm DC resistance limits high-current applications. Verify that the 520 kHz self-resonant frequency suits the target operating band. Consider thermal management within the specified -55°C to 125°C range.

Fixed Inductors Part Context

Part of the 4470 series, which includes various inductance values and tolerance options such as F (1%), G (2%), H (3%), and J (5%). This specific model utilizes an iron core and molded encapsulation typical of the family's general-purpose RF inductor line.

Fixed Inductors Replacement Considerations

Cross-reference other 4470 series variants like 4470-48H or 4470-49J if tolerance adjustments are acceptable. Verify equivalent inductance and current ratings from alternative manufacturers before substitution.
