Procurement Notes
Verify the specific impedance value and current rating against the official Bourns datasheet for the SRF2012-300YA part number. Confirm that the package dimensions and terminal configuration match the required PCB layout. Ensure compliance with environmental regulations such as RoHS if applicable to the final assembly requirements.
Selection Notes
Select this component when space-constrained designs require a four-terminal common mode choke with low DC resistance. The SRF2012A series provides a balance of size and performance suitable for portable electronics. Consider the operating temperature range and current handling capabilities to ensure reliability under expected load conditions.
Part Context
This component belongs to the Bourns SRF2012A series of common mode chip inductors. The series is characterized by its small footprint and multilayer ceramic technology. These inductors are designed for high-frequency noise suppression in modern electronic applications where board space is limited.
Replacement Considerations
Check for direct substitutes within the SRF2012A series or other Bourns common mode chokes with similar impedance and current ratings. Verify pin compatibility and physical dimensions before substitution.
