Procurement Notes
Verify the specific suffix '701Y' matches the required 7 µH inductance and 700 Ω impedance specifications. Confirm that the 4 A current rating and 80 VDC voltage limits align with your circuit requirements. Ensure the SMD package dimensions fit your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when EMI suppression is required for DC lines carrying up to 4 A. The 700 Ω impedance at 1 MHz provides effective noise attenuation. Consider the compact 7x6x3.5 mm footprint for dense board layouts. Verify thermal management capabilities within the -40°C to +125°C operating range for your specific environment.
Part Context
This part belongs to the Bourns SRF7035A series of common mode chokes. The series offers various inductance and impedance values within a standardized compact package. These components are engineered for robust performance in industrial and consumer electronic applications requiring reliable noise suppression.
Replacement Considerations
Check for other SRF7035A variants with matching 7 µH inductance if availability is limited. Ensure any substitute maintains the 4 A current rating and 700 Ω minimum impedance. Verify pin compatibility and mechanical dimensions for direct replacement.
