Procurement Notes
Verify the complete part number including suffixes to ensure correct impedance and tolerance specifications. Confirm package compatibility with your PCB footprint design. Check manufacturer documentation for recommended reflow soldering profiles to maintain component integrity during assembly. Ensure storage conditions align with moisture sensitivity level requirements before installation.
Selection Notes
Select this component when specific common mode noise suppression is required for high-speed digital signals. Evaluate the 300 mA current rating against your circuit's operational requirements. Consider the 200 Ohm impedance at 100 MHz for frequency-specific filtering needs. Verify that the surface mount package fits within your available board space constraints.
Part Context
This component belongs to the SRF2012A series of common mode chokes manufactured by Bourns Inc. The series is characterized by its compact surface mount form factor and suitability for demanding electronic applications. These components are part of Bourns' broader portfolio of passive components designed for signal integrity and electromagnetic interference management.
Replacement Considerations
Consult official Bourns documentation for verified substitute part numbers within the SRF2012A series or equivalent common mode chokes. Ensure any replacement matches the 200 Ohm impedance at 100 MHz and 300 mA current rating. Verify package dimensions and pin configuration compatibility before substitution.
