SRN3010C-470M

Fixed Inductors Overview

The SRN3010C-470M is a semi-shielded surface-mount power inductor from Bourns, designed for automotive applications. It features a ferrite core and wirewound construction within a compact 1212 (3x3x0.9mm) package. The component provides an inductance of 47 µH with a tolerance of ±20%. Key electrical specifications include a maximum DC resistance of 2.28 Ohms, a saturation current of 360 mA, and a maximum DC current rating of 450 mA. It operates reliably between -55°C and +125°C, with a minimum Q factor of 10 at a test frequency of 1 MHz.

Fixed Inductors Feature Summary

• Semi-shielded design to reduce electromagnetic interference
• Ferrite core construction for stable performance
• Automotive-grade reliability across wide temperature ranges

Fixed Inductors Applications

• Automotive electronics systems
• Power supply circuits
• DC-DC converter modules

Fixed Inductors Procurement Notes

Verify the specific suffix 'C' against the official Bourns datasheet to confirm the exact electrical characteristics and packaging configuration. Ensure the ordering part number matches the required inductance value and current ratings for the target application circuit. Cross-reference the RoHS compliance status if environmental regulations apply to the final assembly.

Fixed Inductors Selection Notes

Select this component when a compact 3x3mm footprint is required for high-frequency power filtering. The semi-shielded structure offers a balance between size reduction and magnetic field containment. Consider the 450mA DC current limit and 360mA saturation point to ensure adequate headroom for the specific load conditions in the power management design.

Fixed Inductors Part Context

This part belongs to the SRN series of surface-mount power inductors manufactured by Bourns Electronic Solutions. The series utilizes wirewound technology on ferrite cores to deliver consistent inductance values in small form factors. The SRN3010C variant specifically targets space-constrained designs requiring robust performance in demanding environments.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 47µH inductance, 1212 package dimensions, and similar current ratings. Verify that alternative components offer comparable semi-shielded characteristics and operate within the same -55°C to +125°C temperature range to maintain system compatibility.
