- PFC Boost Stages
- Power Factor Correction Systems
Procurement Notes
Verify the specific datasheet version for the 152905-000 to confirm RoHS compliance details and exact pinout configurations. Ensure the selected variant matches the required current rating and inductance tolerance for your circuit design. Cross-reference the physical footprint dimensions against your PCB layout to guarantee proper through-hole mounting clearance.
Selection Notes
Select this component when designing PFC circuits requiring high-current handling with minimal parasitic effects. The unshielded design may require careful placement to manage electromagnetic interference. Verify that the 4.5 A rated current meets the peak load requirements of the application while maintaining thermal stability within the specified operating temperature range.
Part Context
This part belongs to the Bourns Model 15290x series, which consists of low-parasitic, high-current PFC chokes. These components are engineered to optimize efficiency in power factor correction systems. The series utilizes alloy cores to provide robust performance under high-load conditions typical in industrial and commercial power supplies.
Replacement Considerations
Consult official Bourns documentation for verified substitute part numbers within the 15290x series or equivalent common mode chokes. Ensure any replacement maintains identical inductance, current rating, and physical dimensions to fit existing PCB footprints without redesign.
