Fixed Inductors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging configuration. Confirm that the RoHS3 compliance status aligns with project environmental requirements. Cross-reference the DigiKey part number 1025R-50J-ND with official Delevan datasheets to validate availability and standard delivery timelines prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when an 18 µH inductance with ±5% tolerance is required for through-hole assembly. Ensure the 149 mA current rating meets the circuit's operational demands. Verify that the 3.1 Ohm DC resistance fits the power loss constraints. Confirm compatibility with the -55°C to 105°C operating temperature range for the intended environment.

Fixed Inductors Part Context

This component belongs to the Delevan 1025R series, which consists of fixed, unshielded, molded axial inductors. These parts are characterized by their iron core construction and are designed for reliable performance in various electronic applications. The series offers multiple inductance values while maintaining consistent physical dimensions and mounting styles.

Fixed Inductors Replacement Considerations

The 1025-52K serves as a functional substitute within the same series, sharing identical physical dimensions and similar electrical parameters such as 22 µH inductance and 144 mA current rating. Verify that the slight differences in inductance and current capacity do not impact the specific circuit requirements before implementation.
