Procurement Notes
Verify the specific inductance value required, as the series covers a range from 780 to 1750 µH. Confirm that the 3A current rating and 0.2 mΩ DCR meet your circuit specifications. Ensure the operating temperature range of -40°C to 125°C aligns with your environmental conditions. Check the physical footprint against your PCB layout constraints.
Selection Notes
Select this component when designing PFC stages requiring low parasitic capacitance and high current handling. The low DC resistance minimizes conduction losses, enhancing overall system efficiency. Consider the wide inductance range to tailor performance to specific ripple current requirements. Verify compatibility with your thermal management strategy given the 125°C upper limit.
Part Context
This part belongs to the Bourns Model 15290x Series, which specializes in low-parasitic, high-current PFC chokes. These components are engineered to optimize efficiency in power factor correction systems. The series is designed for applications where minimizing energy loss and parasitic effects is critical for performance.
Replacement Considerations
Consult official Bourns documentation for direct substitutes within the 15290x series. Verify electrical parameters such as inductance, current rating, and DC resistance before substituting. Ensure mechanical dimensions and mounting styles match your existing design requirements.
