SP1210R-224G

Fixed Inductors Overview

The SP1210R-224G is a fixed surface-mount inductor from the API Delevan S1210R series. It features a ferrite drum core and shielded construction to minimize electromagnetic interference. The component provides an inductance of 220 µH with a tolerance of ±2%. Its maximum DC resistance is 20.7 Ohms, supporting a maximum DC current of 100 mA and a saturation current of 87 mA. The device operates within a temperature range of -55 °C to +125 °C and utilizes standard terminations for PCB mounting.

Fixed Inductors Feature Summary

• Shielded surface mount design for reduced electromagnetic interference
• Ferrite drum core construction for stable RF performance
• High Q factor suitable for radio frequency applications

Fixed Inductors Applications

• RF circuits
• Choke applications
• General purpose filtering

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status and lead-free terminal specifications against the latest official datasheet. Ensure the ordering suffix matches the required tolerance grade. Cross-reference package dimensions (1210) with board layout requirements to guarantee proper footprint compatibility during procurement.

Fixed Inductors Selection Notes

Select this component when a shielded 220 µH inductor is required for space-constrained designs. The 1210 package offers a balance between current handling and size. Consider the 87 mA saturation limit for circuit design margins. The shielded nature makes it preferable over unshielded alternatives where magnetic coupling must be minimized in dense layouts.

Fixed Inductors Part Context

This part belongs to the SP1210R series of shielded surface mount power inductors manufactured by API Delevan. The series utilizes a wirewound technique on a ferrite core. Similar parts in the family include the SP1210R-123K and SP1210R-154G, which share the same physical footprint but differ in inductance values and current ratings.

Fixed Inductors Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Equivalent components must match the 220 µH value, 1210 package, and shielding type. Verify that alternative parts meet or exceed the 87 mA saturation current and 20.7 Ohm DCR specifications.
