Overview
The Bourns SRF3216A-261Y is a surface-mount common mode choke from the SRF3216A series, designed for EMI suppression in signal lines. It features an impedance of 260 ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 500 milliohms. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive qualification standards. The physical dimensions are 3.2 mm in length, 1.6 mm in width, and 2.20 mm in height.
Feature Summary
- Provides effective electromagnetic interference (EMI) suppression for high-speed signal lines
- Automotive-grade reliability certified under AEC-Q200 standards
- Compact horizontal surface-mount package suitable for space-constrained PCB layouts
Applications
- High-speed data interface protection
- Automotive electronic systems requiring EMI filtering
- Signal line noise reduction in compact devices
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging and tape-and-reel specifications. Ensure the procurement documentation explicitly states AEC-Q200 compliance if automotive application is required. Cross-reference the impedance value of 260 ohms and current rating of 300 mA with design requirements before ordering.
Selection Notes
Select this component when a low-profile, automotive-qualified common mode choke is needed for signal integrity. The 300 mA current rating suits moderate signal currents. Verify that the 260 ohm impedance at 100 MHz aligns with the target frequency spectrum for noise attenuation. Ensure the 3216 metric footprint fits the available board space.
Part Context
This part belongs to the Bourns SRF3216A series of shielded common mode chokes. The series is characterized by its small form factor and suitability for automated surface-mount assembly. These components are engineered to minimize parasitic effects while providing robust noise filtering capabilities for sensitive electronic circuits.
Replacement Considerations
Check for direct substitutes within the SRF3216A series with different impedance values, such as SRF3216A-221Y, if lower impedance is acceptable. Verify pin compatibility and thermal characteristics before substituting with components from other manufacturers.
