Frequently asked questions
Where is a power inductor like this used?
It is used in switching converters such as buck and boost regulators, where it stores energy during each switching cycle and smooths the output current. Use the value recommended in your converter's datasheet.
Can I replace it with a different inductance value?
Changing the inductance changes ripple current and converter behaviour. Keep to the value in your design, and confirm the saturation and rated current are high enough for your load.
