SRF7035A-302Y

Overview

The Bourns SRF7035A-302Y is a shielded common mode choke designed for surface mount applications. It features an inductance of 22.6 µH at 100 kHz and provides an impedance of 3 kOhms at 100 MHz. The component supports a maximum DC current of 1.2 A with a maximum DC resistance of 72 mOhms. Rated for 80 V DC, it operates within a temperature range of -40°C to +125°C. Physical dimensions are 7 mm x 6 mm x 3.5 mm.

Feature Summary

• Shielded structure minimizes electromagnetic radiation
• Independent winding configuration ensures signal integrity
• Compact footprint suitable for space-constrained designs
• Compliant with AEC-Q200 automotive standards

Applications

• DC power line noise filtering
• EMI suppression in consumer electronics
• Noise reduction in industrial systems
• Switching mode power supply output stages

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm packaging details and material composition. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when high impedance at 100 MHz is required for EMI suppression alongside moderate current handling capabilities. The shielded design makes it suitable for sensitive environments where radiated emissions must be minimized compared to unshielded alternatives.

Part Context

This part belongs to the SRF7035A series of common mode chokes from Bourns. The series offers various inductance and impedance combinations tailored for different noise frequencies while maintaining a consistent compact form factor and automotive-grade reliability profile.

Replacement Considerations

Direct substitutes include other SRF7035A variants with matching electrical parameters. Verify pin compatibility and thermal characteristics when considering cross-brand alternatives.
