Fixed inductors have been widely used in modern electronics and are generally divided into two categories: iron-core inductors and air-core inductors. The 0819-20G inductor belongs to the former. Its operating temperature range is -40 ° C ~ + 85 ° C with excellent performance against temperature and humidity. It has a wide range of applications, ranging from DC input circuits to high-frequency switching power supplies.
The operating principle of 0819-20G inductor is based on a well-known law of physics, Faraday\'s law of induction. According to this law, a voltage is induced in a closed loop when a changing magnetic field passes through it. In the 0819-20G, there is an iron core at the centre and the windings are wrapped around it. As the current flows through the windings, the changing magnetic field induces voltage in the coil, which is proportional to the rate of change of current passing through the coil.
The other important factor affecting the operation of 0819-20G is the self-inductance of the core material. As the magnetic field increases, the material’s self-inductance induces an opposing current in the coil, which in turn causes a voltage drop proportional to the amount of current passing through it. Additionally, the air gap between the two core components also influences the induced current, as it adds to the resistance of the total circuit. Typically, the higher the air gap, the greater the induced current and the higher the voltage drop.
The 0819-20G inductor finds its application mainly in DC input circuits, as it can provide a steady voltage for the input power supply. It is also commonly used in switching power supplies, as it helps reduce the noise generated from the power supply’s high frequency switching actions. Other uses include signal conditioning circuits, filter circuits and chopper circuits.
To sum up, the 0819-20G inductor is a highly reliable and efficient component, which is suitable for various applications, ranging from DC input circuits to high-frequency switching power supplies. Its simple design and operating principle make it one of the most popular inductors in the electronics industry.
