- Generally speaking, it is considered to be a good idea to set the ripple current ⊿IL to about 30% of the load current Iout.

- Note: ripple current
- A circuit which conducts a high current, such as a digital circuit, requires a power inductor with an inductance that does not decrease due to a high current, that is to say, a power inductor with a good DC superposition characteristic. This means that because the inductance does not decrease, the ripple currents are kept constant, and stable circuit operation can be maintained. In the case of winding Metal Alloy, because it is difficult for magnetic saturation to occur in comparison to ferrite, it possesses a superior DC superposition characteristic.
