SMD inductors in open circuit detection

SMD inductor (Chip inductors), also known as power inductors, high-current inductors, and surface-mounted high-power inductors.It features miniaturization, high quality, high energy storage and low resistance.

SMD inductor mainly has the functions of filtering, oscillation, frequency division and energy storage boosting in the circuit. Different inductors have different working principles in the circuit.

In the bridge rectifier circuit and the load between a series of inductors constitute a lazy inductor filter circuit.The C filter circuit can be formed by adding a capacitor to the inductor filter circuit.

In the filter circuit of inductor, the inductance of inductor is very low for dc component, so the inductance is in the state of short circuit.The voltage falls mostly on the load.The higher the frequency, the higher the inductance.

In practice, it can be used in series or in parallel. When the SMT inductance is used in series, the total inductance is the sum of the two inductors. When the inductance is used in parallel, the reciprocal of the total inductance is the sum of the reciprocal of each inductance.

Inductance in the filter circuit, mainly to stabilize the current and filter the noise in the current, to prevent electromagnetic interference, the circuit is generally the use of inductance energy storage components inductor current can not mutate nature, the inductance rectifier circuit load phase series, so can play a role in filtering.
