Procurement Notes
Verify the specific suffix YA against official Bourns documentation to confirm impedance and tolerance specifications. Ensure the procurement channel provides valid traceability for AEC-Q200 compliance. Cross-reference the package dimensions with the latest datasheet to confirm compatibility with automated placement equipment and soldering profiles.
Selection Notes
Select this component when automotive reliability and small form factor are required for signal integrity. The 100 Ohm impedance rating targets specific frequency ranges for noise attenuation. Verify that the operating temperature range covers the intended application environment. Confirm that the physical dimensions fit within the designated board area constraints.
Part Context
This part belongs to the SRF2012A series of common mode chokes from Bourns Inc. The series is characterized by its miniature size and suitability for high-density mounting. It serves as a passive component for electromagnetic interference suppression in modern electronic assemblies.
Replacement Considerations
Consult official Bourns substitution guides for verified equivalents. Do not assume functional interchangeability based solely on similar package dimensions or nominal impedance values without verifying electrical characteristics and thermal ratings.
