Fixed inductors are passive electronic components that are used to store energy in the form of a magnetic field, thus producing the desired inductance. In this article, we will discuss the application field and working principle of ER1840-36KP, one of the most popular fixed inductors.

ER1840-36KP is a fixed inductor designed for use in high frequency switching power supplies, DC-to-DC converters, filter circuits, and other power supply designs. It is a compact, high power, low profile inductor with a high saturation current, making it suitable for high power applications. ER1840-36KP has a high electrical efficiency and provides excellent EMI performance.

ER1840-36KP is typically used in applications such as controlling power flow in DC-DC converters and high frequency switching power supplies. It is also suitable for filter circuits and capacitive divider networks. In DC-DC converters, ER1840-36KP is used as an inductor, allowing a higher voltage to be created to power high voltage circuits. ER1840-36KP can also be used in power supplies to reduce the amount of noise generated by the electrical components.

The working principle of ER1840-36KP is based on the effects of magnetic fields on electric current. It consists of a core made of high permeability ferrite material, two wire windings, and two terminals attached to the ends of the core. When current passes through the wire windings, it creates a magnetic field which interacts with the core, inducing a voltage in the windings. This voltage is then accessed from the terminals.

The inductance of ER1840-36KP is determined by the number of turns of the wire windings, the diameter of the coil, the material of the core, and the air gap in the core. It has an operating temperature range of -40°C to +105°C, making it suitable for industrial applications. The ESR (Equivalent Series Resistance) of the coil is usually low, resulting in high frequency switching power supplies with minimal losses.

ER1840-36KP is a reliable and versatile fixed inductor that is suitable for high power applications. It is capable of producing high inductance, and its compact size makes it ideal for use in tight spaces. Its minimal losses and low ESR make it suitable for use in high frequency switching power supplies and other power supply designs.
