4590R-825J

Fixed Inductors Overview

The Delevan 4590R-825J is a fixed power inductor from the 4590/R series, featuring an axial leaded termination style for through-hole PCB mounting. It utilizes a ferrite drum core with a wirewound construction and offers an inductance of 8.2 mH with a ±5% tolerance. The component supports a maximum DC current of 320 mA and has a maximum DC resistance of 6.44 Ohms. It operates within a temperature range of -55°C to +125°C and is tested at 1 kHz.

Fixed Inductors Feature Summary

• Axial leaded design suitable for through-hole printed circuit board mounting
• Ferrite drum core construction providing high current capability
• Wide operating temperature range for robust environmental performance

Fixed Inductors Applications

• Power supply filtering circuits
• General purpose power electronics
• Signal processing applications requiring stable inductance

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' confirms the 5% tolerance variant when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Ensure axial lead dimensions match the target PCB footprint before integration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in a through-hole package. The 320 mA current rating suits moderate power applications. Compare against shielded SMD alternatives if space constraints exist. Verify that the 6.44 Ohm DC resistance meets the circuit's voltage drop requirements.

Fixed Inductors Part Context

This part belongs to the Delevan 4590/R series of power inductors. The series is characterized by axial leads and ferrite cores. Similar parts include the 4590-825K which shares physical dimensions but differs in tolerance. The 4590R-125K offers lower inductance within the same form factor.

Fixed Inductors Replacement Considerations

The 4590-825K is a compatible alternative with identical electrical ratings except for the 10% tolerance versus 5%. Ensure the replacement maintains the axial lead configuration for existing PCB layouts.
