SRF4530A-110Y

Overview

The Bourns SRF4530A-110Y is a surface-mount common mode choke featuring an 11 µH inductance with -30%/+50% tolerance. It supports a maximum DC current of 360 mA and exhibits a maximum DC resistance of 500 mOhms. The component provides 600 Ohms impedance at 10 MHz and operates within a temperature range of -55°C to +150°C. Its physical dimensions are 4.5 mm x 3.2 mm x 3.0 mm, utilizing a ferrite core construction.

Feature Summary

• Halogen-free construction for environmental compliance
• AEC-Q200 qualified for automotive reliability standards
• High operating temperature capability up to 150°C

Applications

• Automotive electronic circuits requiring AEC-Q200 components
• Common mode noise suppression in data lines
• Signal integrity protection in compact PCB designs

Procurement Notes

Verify the specific suffix 'Y' corresponds to halogen-free status and reel packaging configuration as defined by Bourns documentation. Confirm that the AEC-Q200 qualification applies to this specific variant. Ensure the selected package matches the required tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this component when high-temperature operation up to 150°C is required alongside strict automotive reliability standards. The 360 mA current rating suits low-power signal line filtering applications. Verify that the 11 µH inductance value aligns with the target frequency response requirements for the specific circuit design.

Part Context

This part belongs to the Bourns SRF4530A series of common mode chip inductors. The series is characterized by its small footprint and high thermal stability. These components are designed for surface-mount technology and are specifically engineered to meet the rigorous demands of automotive electronics manufacturing.

Replacement Considerations

Check for direct substitutes within the SRF4530A series or other Bourns automotive-grade common mode chokes with identical 4.5x3.2mm footprints. Ensure any replacement maintains the 11 µH inductance and 360 mA current rating while preserving AEC-Q200 certification.
