Fixed Inductors

Inductors are electrical components that create a magnetic field when current passes through them. Fixed inductors are a type of inductor whose inductance remains constant with changes in the applied current or frequency. The ER1537-04KM is a fixed inductor designed for use in power line applications such as battery-powered equipment and switched mode power supplies.

Application Fields

The ER1537-04KM fixed inductor is primarily used in motor control applications such as electric cars, machine tools, and robotics. It is also used in the power line of alternating current (AC) devices such as refrigerators, air conditioners, and washing machines. In the power line, the inductor blocks interference from electromagnetic signals that can cause equipment malfunctions. It is also used to reduce voltage drop in motors and to reduce arcing in electrical switches.

The ER1537-04KM inductor is also used in the power lines of DC (DC) power supplies. In a DC power supply, the inductor is used to filter out noise and regulate the voltage to acceptable levels. This ensures that all connected devices receive clean, steady power.

Working Principle

The working principle of the inductor is based on Faraday\'s Law of Induction. This law states that when an electrical current passes through a conductor, a magnetic field is created around it. When a voltage is applied to the inductor, this magnetic field induces a voltage in the coil in the same direction as the applied voltage. This current is then conducted to the desired output.

The ER1537-04KM is a wound coil inductor, meaning it is made up of multiple wire turns wound together to form a coil. This creates a greater magnetic field strength and a larger induced voltage than a single wire inductor. By varying the number of turns, the inductance of the inductor can be adjusted to meet the needs of the application.

The inductor is constructed of a ferromagnetic core wound with a formvar insulated enameled copper wire. The ferromagnetic core material increases the inductance of the inductor while the enameled wire insulation prevents magnetic fields from interacting with other components in the device.

Conclusion

The ER1537-04KM fixed inductor is a reliable, cost-effective inductor designed for use in power line applications. Its construction from a ferromagnetic core and formvar insulated enameled wire ensures maximum efficiency with minimal power losses. With its wide range of applications in motor control, alternating current, and direct current power supplies, the ER1537-04KM is an ideal choice for any electronic device requiring a reliable power line inductor.
