SRF4532TA-282Y

Overview

The Bourns SRF4532TA-282Y is an automotive-grade common mode chip inductor from the SRF4532TA series. It features a ferrite core and shielded construction within a 1812 (4.5 x 3.2 x 2.8 mm) surface-mount package. Key electrical specifications include an inductance of 10 µH at 100 kHz, a common mode impedance of 2800 Ω at 100 MHz, and a maximum DC current rating of 900 mA. The component has a maximum DC resistance of 350 mΩ and operates reliably between -55°C and +125°C.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Shielded design to minimize electromagnetic interference
• High impedance performance across broad frequency ranges

Applications

• EMI suppression in automotive signal lines
• Noise filtering for high-speed data interfaces
• Common mode noise reduction in vehicle electronics

Procurement Notes

Verify the specific suffix 'Y' matches the required tape-and-reel packaging configuration for your assembly line. Confirm that the AEC-Q200 qualification status is explicitly documented in the official manufacturer datasheet for your target application. Ensure the operating temperature range of -55°C to +125°C aligns with your environmental requirements before finalizing procurement.

Selection Notes

Select this component when a compact 1812 footprint is required for automotive applications demanding high current handling up to 900 mA. The 10 µH inductance and 2800 Ω impedance at 100 MHz make it suitable for broadband noise suppression. Compare against non-shielded alternatives if space constraints allow, but prioritize this shielded version for superior EMI performance in dense PCB layouts.

Part Context

This part belongs to the Bourns SRF4532TA series of common mode chokes designed specifically for automotive environments. The series utilizes ferrite cores to achieve high impedance in a small form factor. The TA designation typically indicates automotive qualification and shielded construction, distinguishing it from standard commercial grade components in the broader SRF4532 family.

Replacement Considerations

Direct substitutes within the same series include SRF4532TA-901Y and SRF4532TA-282Y variants with different impedance values. Verify pin compatibility and thermal characteristics when cross-referencing with other manufacturers' automotive-grade common mode chokes in the 1812 package.
