SRP0412F-2R2M

Fixed Inductors Overview

The Bourns SRP0412F-2R2M is a shielded surface-mount power inductor with a nominal inductance of 2.2 µH and a tolerance of ±20%. It features a metal alloy powder core and a maximum DC resistance (DCR) of 57.6 mΩ. The component supports a saturation current (Isat) of 5.5 A and a rated RMS current of 4.2 A. Operating within a temperature range of -40°C to +125°C, it measures 4.3 mm x 4.1 mm x 1.0 mm.

Fixed Inductors Feature Summary

• Shielded construction minimizes electromagnetic radiation for cleaner circuit operation.
• Metal alloy powder core provides high saturation current capabilities.
• Low profile design facilitates compact PCB layouts.

Fixed Inductors Applications

• DC-DC converter circuits
• Power supply modules
• Telecommunications equipment

Fixed Inductors Procurement Notes

Verify the specific suffix '2R2M' against official Bourns documentation to confirm the 2.2 µH value and 57.6 mΩ DCR specifications. Ensure the ordering part number matches the required tape-and-reel packaging format. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a low-profile, shielded inductor is required for space-constrained designs. The metal alloy core offers superior performance compared to standard iron cores regarding saturation characteristics. Verify that the 4.2 A RMS and 5.5 A Isat ratings meet the thermal and peak load requirements of the target application circuit.

Fixed Inductors Part Context

This part belongs to the SRP0412F series from Bourns Inc., which specializes in compact, shielded power inductors. The series utilizes a flat-wire structure to achieve low DC resistance and reduced buzz noise. These components are designed for high-efficiency power delivery in modern electronic systems requiring small form factors.
