The inductance of a typical electronic circuit is an air-core coil or a coil with a magnetic core that can withstand lower voltages with less current.
The chip power inductor with a magnetic core to enhance their own product saturation of the magnetic inductance at the same time a larger range, the main feature is thick wire wound system can withstand tens of security, hundreds, thousands, or even tens of thousands Ann.
The main parameters of the chip power inductor: inductance, inductor properties.
The greater the inductance, the better the energy storage effect, the smaller the ripple, but the greater the inductance, the greater the required size, the greater the DCR, the more the partial pressure.
Affect the power supply, and the inductor energy storage hours, the filtering effect will be worse, so choose the power inductor should be considered in many ways.
