SRF7035A-301Y

Overview

The Bourns SRF7035A-301Y is a surface-mount common mode choke from the SRF7035A series, designed for electromagnetic interference suppression in DC power lines. It features an inductance of 4 µH at 100 kHz and a minimum impedance of 225 Ω at 1 MHz. The component supports a maximum DC current of 5.0 A with a maximum DC resistance of 10 mΩ. Rated for 80 V DC, it operates within a temperature range of -40°C to +125°C. The shielded construction measures 7 mm x 6 mm x 3.5 mm.

Feature Summary

Shielded structure provides low radiation and effective EMI suppression
Independent winding configuration with sector winding design
High current capability suitable for demanding power applications
Compact footprint optimized for space-constrained surface mount designs

Applications

DC/DC converters
Switching mode power supplies
Power system noise suppression
Consumer electronics

Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 4 µH inductance and 5 A current rating. Confirm compliance with AEC-Q200 standards if automotive qualification is necessary. Ensure the package dimensions align with the PCB layout requirements. Check RoHS and halogen-free status against project constraints. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when high current handling and compact size are critical for DC line filtering. The 10 mΩ DC resistance minimizes power loss in high-current paths. The 80 V DC rating ensures safety margin for various voltage levels. Consider the 225 Ω impedance at 1 MHz for effective high-frequency noise attenuation. Verify thermal performance within the specified operating temperature range.

Part Context
