1812R-220J

Fixed Inductors Overview

The Delevan 1812R-220J is a surface-mount fixed inductor designed for RF applications. It features an unshielded construction with a ferrite core, housed in a standard 1812 (4532 metric) package measuring 4.83 mm in length, 3.4 mm in width, and 3.4 mm in height. The component provides a nominal inductance of 22 nH with a tolerance of ±5%. It supports a maximum DC current of 1.23 A and exhibits a maximum DC resistance of 100 mΩ. The device operates within a temperature range of -55°C to +125°C.

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as API Delevan and Delevan are associated with this part number. Confirm RoHS compliance status and lead-free finish details against the latest official datasheet before procurement. Ensure the unshielded configuration aligns with your circuit's electromagnetic interference requirements.

Fixed Inductors Selection Notes

Select this component when a low-value, unshielded inductor is required for RF or general-purpose applications. The 1812 package offers a balance between current handling capability and board space efficiency. Consider the 100 mΩ DC resistance and 1.23 A rating to ensure adequate performance under expected load conditions without excessive heat generation.

Fixed Inductors Part Context

This component belongs to the 1812R series of fixed inductors manufactured by API Delevan. The series includes various inductance values within the 1812 surface-mount package. These inductors are characterized by their unshielded design and ferrite cores, making them distinct from shielded power inductors in the same form factor family.

Fixed Inductors Replacement Considerations

Cross-reference with other 1812 package unshielded inductors offering 22 nH ±5% tolerance. Verify that substitute components match the 1.23 A current rating and 100 mΩ DCR specifications to maintain circuit integrity.
