Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm physical orientation and terminal configuration. Ensure that the selected variant matches the required mounting style and dimensional constraints for the target PCB layout. Cross-reference electrical parameters such as inductance and current ratings with the latest datasheet to guarantee compatibility with system requirements.
Selection Notes
Select this component based on its 1 mH inductance and 1.2 A current handling capability for EMI suppression tasks. Consider the vertical mounting profile and radial leads when designing the mechanical assembly. Evaluate the thermal performance within the specified -55°C to +105°C range to ensure stability under varying environmental conditions during operation.
Part Context
This component belongs to the Bourns 7300 series of common mode filters and chokes. It is engineered for robust noise reduction in electronic circuits requiring reliable interference mitigation. The design supports standard through-hole manufacturing processes while delivering consistent electrical performance for signal integrity preservation.
Replacement Considerations
The 7351-V-RC is a documented alternative within the same product family, offering similar electrical characteristics but potentially differing in physical orientation or package style. Verify dimensional compatibility before substitution.
