SRF4532-110Y

Overview

The Bourns SRF4532-110Y is a surface-mount common mode choke from the SRF4532 series, housed in an 1812 (4.5mm x 3.2mm x 2.8mm) package. It features an inductance of 11 µH at 100 kHz and a maximum DC current rating of 300 mA. The component exhibits a maximum DC resistance of 800 mOhms and provides 700 Ohms impedance at 10 MHz. Constructed with ferrite core material, it operates within a temperature range of -40°C to +125°C and carries RoHS compliance.

Feature Summary

• Dual-line common mode filtering for signal integrity protection
• Ferrite core construction for high-frequency noise suppression
• RoHS compliant molded design suitable for automated assembly

Applications

• High-speed data line filtering
• USB interface noise suppression
• General purpose EMI/RFI mitigation in compact electronics

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm tolerance and packaging specifications. Ensure the ordering quantity matches the required reel or cut-tape configuration. Cross-reference the impedance and current ratings with the target circuit requirements before finalizing procurement to avoid performance mismatches.

Selection Notes

Select this component when space-constrained designs require 1812 footprint common mode chokes. The 300 mA current rating suits low-power signal lines rather than power delivery paths. Verify that the 11 µH inductance meets the specific frequency attenuation needs of the application circuit.

Part Context

This part belongs to the Bourns SRF4532 series of common mode chip inductors. These components are designed for surface mount technology and utilize ferrite cores to provide effective electromagnetic interference suppression in small form factors suitable for modern PCB layouts.

Replacement Considerations

Consult official substitution guides for equivalent parts within the same series or alternative manufacturers offering identical 1812 dimensions and electrical characteristics.
