SRN2010-R47M

Fixed Inductors Overview

The SRN2010-R47M is a surface mount semi-shielded power inductor from Bourns, featuring a 470 nH nominal inductance with a ±20% tolerance. It utilizes a drum core wirewound construction and offers a maximum DC resistance of 42 mOhms. The component supports a rated current of 3.3 A and a saturation current of 3.8 A. Its compact nonstandard package measures approximately 2 mm in length and 1.02 mm in height, designed for high-density PCB layouts.

Fixed Inductors Feature Summary

• Semi-shielded wirewound construction to minimize electromagnetic interference
• Miniature low-profile design suitable for space-constrained applications
• Drum core technology providing stable performance under load

Fixed Inductors Applications

• DC-DC converter output filtering
• Point-of-load regulation circuits
• Portable electronic device power management

Fixed Inductors Procurement Notes

Verify the specific package dimensions against the official datasheet, as the SRN2010 series may exhibit slight variations compared to standard footprints. Confirm that the 3.3 A rated current and 3.8 A saturation current meet the thermal and operational requirements of the target circuit design before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a low-profile, semi-shielded inductor is required for high-frequency switching applications. The 470 nH value is optimal for buck converters operating at higher frequencies. Ensure the PCB layout accommodates the specific nonstandard footprint dimensions provided in the manufacturer's documentation.

Fixed Inductors Part Context

This part belongs to the SRN2010 series of fixed inductors by Bourns Inc., which focuses on miniature power solutions. The series includes various inductance values ranging from 0.24 to 2.2 μH, catering to different power supply designs. The SRN2010-R47M specifically addresses the need for compact shielding in modern consumer electronics.

Fixed Inductors Replacement Considerations

The SRP2010-R47M is a shielded alternative within the same series offering similar electrical characteristics but with full shielding. The SRN3012BTA-R47M provides higher current handling capabilities due to its larger 3x3x1 mm package size.
