SRF1306-350Y

Overview

The Bourns SRF1306-350Y is a surface mount common mode choke designed for EMI filtering in line filter circuits. It features an inductance of 35 µH at 100 kHz and provides 400 Ohms impedance at 5 MHz. The component supports a maximum DC current of 2.7 A with a typical DCR of 35 mOhm. It operates within a temperature range of -40°C to +125°C and has a voltage rating of 50 VDC.

Feature Summary

• Surface mount construction for automated assembly
• Common mode noise suppression capability
• High saturation current handling

Applications

• EMI filtering in power supply lines
• Signal line protection in electronic equipment
• Noise suppression in data communication interfaces

Procurement Notes

Verify the exact datasheet version from Bourns Inc. before integration. Confirm that the 35 µH inductance and 2.7 A current ratings align with your circuit requirements. Ensure the surface mount package dimensions fit your PCB layout constraints. Check for any specific handling or storage recommendations provided in the official documentation.

Selection Notes

Select this component when high common mode impedance is required at 5 MHz alongside moderate DC current capacity. The low DCR minimizes power loss in the signal path. Consider the operating temperature range if the application involves thermal stress. Compare against other SRF1306 variants if different inductance values are needed.

Part Context

This part belongs to the Bourns SRF1306 series of shielded common mode chokes. These components are engineered for compact designs requiring effective EMI suppression. The series offers various inductance options to suit different frequency and current applications while maintaining a consistent footprint.

Replacement Considerations

Check for direct substitutes within the SRF1306 series with compatible inductance and current ratings. Verify pinout compatibility if replacing with similar components from other manufacturers. Ensure electrical parameters meet or exceed original specifications.
