SRF4530A-220Y

Overview

The Bourns SRF4530A-220Y is a dual-line common mode choke designed for surface mount applications. It features a ferrite core and offers an inductance of 22 µH at 100 kHz with a maximum DC current rating of 310 mA. The component exhibits an impedance of 1.2 kOhms at 10 MHz and a maximum DC resistance of 600 mOhms. Housed in a compact 4.5 mm x 3.2 mm x 3.0 mm package, it operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Dual-line configuration for effective noise suppression in differential signal lines
• AEC-Q200 qualified for automotive reliability standards
• Halogen-free construction compliant with RoHS directives

Applications

• CANbus network noise suppression
• Automotive electronic signal line protection
• High-speed data interface filtering

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm halogen-free status and tape-and-reel packaging specifications. Ensure the selected variant matches the required AEC-Q200 certification level for your target application environment. Cross-reference the impedance tolerance and DC resistance values with your circuit design constraints before finalizing procurement.

Selection Notes

Select this component when designing for automotive CANbus or similar high-noise environments requiring AEC-Q200 compliance. The 310 mA current rating suits low-power signal lines rather than power delivery. Consider the 4.5x3.2mm footprint for space-constrained PCB layouts. Verify that the 1.2 kOhm impedance at 10 MHz aligns with the frequency spectrum of interference you intend to suppress.

Part Context

This part belongs to the Bourns SRF4530A series of chip inductors. The series is engineered specifically for suppressing electromagnetic interference in automotive communication buses. The model number indicates a 22 µH inductance value within the standard product lineup.

Replacement Considerations

Direct substitutes include other AEC-Q200 qualified common mode chokes from Bourns with identical 4.5x3.2mm footprints and comparable 22 µH ratings. Verify pin compatibility and impedance curves before substitution.
