Overview
The Bourns SRF7035A-132Y is a surface-mount common mode choke with a nominal inductance of 10.4 µH and an impedance of 1.3 kΩ at 1 MHz. It supports a maximum current rating of 2.5 A and features a low DC resistance of 25 mΩ. The component operates within a temperature range of -40°C to +125°C and has a rated voltage of 80 V DC. Its compact shielded package measures 7 mm x 6 mm x 3.5 mm, making it suitable for space-constrained power line filtering applications.
Feature Summary
- Shielded construction designed to minimize electromagnetic radiation
- Separated winding configuration for enhanced isolation
- High current handling capability within a compact footprint
- Compliance with AEC-Q200 automotive qualification standards
Applications
- Power system noise suppression
- DC/DC converter output filtering
- Switching mode power supply (SMPS) EMI reduction
- Consumer electronics power line protection
Procurement Notes
Verify the specific suffix '132Y' against official Bourns documentation to confirm the exact inductance and impedance values. Ensure the procurement channel provides traceability for AEC-Q200 compliance if automotive application is required. Confirm packaging details such as reel quantity directly with the supplier prior to ordering.
Selection Notes
Select this component when a compact, shielded common mode choke is needed for high-current DC lines. The 2.5 A rating and 1.3 kΩ impedance at 1 MHz make it suitable for suppressing broadband noise in power delivery networks. Consider the 80 V DC rating and wide temperature range for robust industrial or automotive environments.
Part Context
This part belongs to the Bourns SRF7035A series of surface-mount common mode chokes. The series offers various inductance and impedance combinations within a standardized 7x6x3.5 mm package. The SRF7035A-132Y specifically targets applications requiring significant current handling alongside effective high-frequency noise attenuation.
Replacement Considerations
Consult Bourns official cross-reference tools for verified substitutes. Ensure any replacement maintains the 7x6x3.5 mm footprint, 2.5 A current rating, and 1.3 kΩ impedance at 1 MHz to preserve circuit performance.
