Fixed Inductors

Fixed inductors, often referred to as coils, are devices that store energy in an inductive reactance, an electrical property that resists a change in current. This is enabled by a magnetic field generated by the coil, which opposes any change in the current. Fixed inductors are used in many electrical applications, including applications requiring high power or in applications in which precise current control is required.

1840R-35F Application Field and Working Principle

The 1840R-35F is a fixed inductor that is primarily used in AC/DC converters, switch-mode power converters, and inductive heating applications. It is designed to operate over a wide range of frequencies, including between zero to 35kHz. The device is housed in a molded plastic casing and has a lead attached for easy soldering. Its rated voltage is as low as 1V, with a maximum voltage of 500V. The 1840R-35F is designed to be energy efficient, with a low current and energy consumption rate.

To understand the working principle of the 1840R-35F, it is necessary to look at the fundamentals of inductors and how they can be used. The device operates by creating a magnetic field around the coil. When an alternating current is applied to the coil, the changing current causes the magnetic field to fluctuate, creating an opposing current. This opposing current is known as a back electromotive force (BEMF), whose strength is proportional to the amount of current it is opposing. As the current builds up, the opposing force also increases, creating a back-and-forth current flow in the inductor.

The 1840R-35F also has a surge-resistant feature, which helps protect against sudden, high currents. This feature allows the device to remain stable in the event of a sudden surge, yet still maintain its rated current and voltage. This ensures that the device remains protected against unexpected surges, while still providing the desired output.

The 1840R-35F is an extremely versatile fixed inductor, as it can be used in a wide range of applications. It can be used in AC/DC converters, switch-mode power converters, inductive heating, and other power-related applications. The device’s low current and energy consumption, as well as its surge-protection feature, make it an ideal choice for various applications.
