Fixed Inductors Applications

• RF signal processing circuits
• Inductive filtering applications
• General purpose RF coil implementations

Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact tolerance and current ratings, as variations exist within the 2500 series. Confirm RoHS compliance status directly with the supplier, as historical data indicates non-compliance for certain variants in this line. Ensure the ordering quantity matches the manufacturer's standard reel packaging requirements to avoid handling discrepancies.

Fixed Inductors Selection Notes

Select the 2500-02F when a 300 µH inductance with tight ±1% tolerance is required for RF applications. This component is appropriate for designs needing high Q factors around 790 kHz and operation up to 105°C. Consider the unshielded nature of the part for layout planning to minimize mutual inductance effects with nearby components.

Fixed Inductors Part Context

This component belongs to the Delevan 2500 series of fixed RF inductors. The series offers various inductance values and tolerances, all sharing a common molded axial form factor. These parts are engineered for reliability in radio frequency environments, providing consistent performance across wide temperature ranges compared to standard general-purpose inductors.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include the 2500-10J and 2500-12F, though these differ in inductance and current ratings. Verify that any replacement maintains the required 300 µH value and 122 mA current capacity to ensure circuit compatibility.
