Fixed Inductors are frequently used in devices that generate high-frequency alternating current (AC) and direct current (DC) signals. The 7443320100 is a type of fixed inductor capable of limiting the current, storing energy, or serving as a filter. The 7443320100 can either be air- or powder-core wound. This article will discuss the 7443320100\'s application field and working principle.
<
Application Field
- A/D Converters
- The 7443320100 often serves as an EMI filter in A/D converters, as devices such as these can emit EMI signals that interfere with nearby circuitry.
- DC-to-DC Controllers
- The 7443320100 also acts as a switching filter to reduce high-frequency noise generated by DC-to-DC controllers. This noise can interrupt communications and affect the accuracy of various circuits.
- Power Supplies
- The 7443320100 is used as an EMI filter to prevent EMI signals from entering the power supply. This is needed to ensure the power supply is not interfered with by unwanted signals and can operate optimally.
- DC Motors
- The 7443320100 is often used in DC motors to increase the torque and smooth out the ON/OFF periods.
Working Principle
The 7443320100 works through inductance. Inductance is a property of an electrical circuit or component, whereby an electric current flowing through it induces a magnetic field. The amount of background magnetic field affects the inductance, meaning that two identical inductors will have different amounts of inductance if placed in different environments.- When an alternating current is applied to the 7443320100, the changing magnetic field due to the current flow causes the inductor’s core material to become magnetized.
- The magnetic field produced by the 7443320100 will attract nearby electrical charges and oppose the current flow.
- The amount of interaction between the 7443320100 and the current determines the magnitude of the inductance.
