SRF3216A-361Y

Overview

The Bourns SRF3216A-361Y is a two-line surface-mount common mode choke designed for EMI suppression in signal and data lines. It features an impedance of 360 Ohms at 100 MHz, a maximum DC resistance of 600 milliohms, and a current rating of 300 mA. The component operates within a temperature range of -40°C to +125°C and holds AEC-Q200 automotive qualification. Its compact dimensions are 3.20 mm x 1.60 mm x 2.20 mm.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed data and signal transmission lines
• Automotive-grade reliability certified under the AEC-Q200 standard for harsh environment durability
• Utilizes a shielded horizontal surface-mount package to minimize footprint and prevent lead-frame radiation

Applications

• EMI suppression in CANbus networks
• Signal line filtering in automotive electronics
• Noise reduction in consumer electronic interfaces
• Telecommunications equipment signal integrity protection

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's datasheet to confirm impedance tolerance and terminal plating specifications. Ensure the selected packaging option aligns with automated assembly requirements. Confirm that the 300 mA current rating meets the operational load conditions of the target circuit design before finalizing procurement.

Selection Notes

Select this component when space constraints require a 3216 metric footprint for signal line filtering. The 360 Ohm impedance value targets noise frequencies around 100 MHz. Verify that the 600 milliohm DC resistance does not cause excessive voltage drop in low-voltage signal paths. Consider the AEC-Q200 certification if the application demands automotive-grade reliability standards.

Part Context

This part belongs to the Bourns SRF3216A series of common mode chip inductors. The series is engineered for compact designs requiring efficient EMI suppression in tight spaces. These components are widely used in modern electronics where signal integrity is critical and physical size limitations restrict the use of larger through-hole or standard surface-mount filters.

Replacement Considerations

ACE1V2012-361-R by Eaton Electronics Division is a documented substitute. Note that the ACE1V2012 uses a 2012 metric footprint, which differs from the 3216 metric size of the SRF3216A-361Y. Verify PCB layout compatibility and mounting hole alignment before substituting.
