Procurement Notes
Verify the specific suffix YA against official Bourns documentation to confirm shielding type and tolerance. Ensure the requested quantity matches factory pack specifications. Confirm AEC-Q200 compliance requirements align with your target application's regulatory standards before finalizing procurement.
Selection Notes
Select this component when high-frequency noise suppression is required in tight spaces. The 500 Ohm impedance at 100 MHz targets specific EMI frequencies. Verify that the 100V DC rating exceeds the circuit's operating voltage. Consider the -40°C to +125°C range for environmental exposure.
Part Context
This part belongs to the SRF2012A series of common mode chokes. The series provides various impedance values in a standardized small footprint. These components are engineered for suppressing common mode noise in high-speed digital and analog signal paths across industrial and automotive sectors.
Replacement Considerations
Check Bourns datasheets for other SRF2012A variants with matching impedance and current ratings. Ensure substitute parts maintain AEC-Q200 qualification if automotive use is intended. Verify pin compatibility and thermal characteristics before integration.
