2500R-58J

Fixed Inductors Overview

The Delevan 2500R-58J is a molded, unshielded axial lead RF inductor designed for printed circuit board mounting. It features an inductance of 4.3 mH with a tolerance of ±5%. The component supports a maximum DC current of 60 mA and exhibits a maximum DC resistance of 46 Ohms. Key electrical characteristics include a minimum Q factor of 80 and a self-resonant frequency of 1.35 MHz. Physical dimensions are 18.8 mm in length and 6.1 mm in diameter.

Fixed Inductors Feature Summary

• Molded construction provides mechanical stability for axial lead components
• Unshielded design suitable for applications where magnetic interference is not critical
• Standard axial termination facilitates through-hole PCB integration

Fixed Inductors Applications

• RF circuit filtering
• Signal processing networks
• Impedance matching stages

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets have transitioned. Confirm RoHS compliance status directly with the supplier, as historical data varies by production batch. Ensure the axial lead pitch matches the target PCB footprint before ordering. Cross-reference the part number against current distributor catalogs to confirm availability and exact datasheet revisions.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required within a compact axial form factor. The unshielded nature necessitates careful layout planning to prevent coupling with adjacent traces. Verify that the operating current remains below the 60 mA limit to avoid saturation or excessive heating. Consider the self-resonant frequency relative to the target signal bandwidth to ensure effective performance.

Fixed Inductors Part Context

This component belongs to the 2500/R series of fixed RF inductors manufactured by Delevan. The series utilizes molded technology to create robust, unshielded coils with axial leads. These parts are categorized under RF inductors and are intended for specialized electronic applications requiring precise inductive values in a standard through-hole package.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 4.3 mH axial RF inductors from different manufacturers, provided they match the 60 mA current rating and physical dimensions. Verify that alternative parts maintain similar Q factors and self-resonant frequencies to ensure circuit compatibility without redesign.
