Fixed Inductors

Inductors play a critical role in the manufacturing of various electronic components, such as power supplies, transformers, amplifiers and radio frequency circuits. Fixed inductors are among the most important types of inductors. The ER1840-05KP fixed inductor is a versatile and cost-effective component ideal for various industrial and commercial applications.The ER1840-05KP is a radial leaded, through-hole inductor featuring a ferrite core with a cylindrical shape and an electronic grade windings. It is a variable inductor, meaning its inductance value can be readjusted or recalibrated. It has two pins, allowing it to be connected to a circuit. The inductance values in this component range from 2.2uH to 1000uH.The ER1840-05KP can be used in a wide range of electronic circuits, including high frequency switching power supplies, DC-DC converters, AC adapter circuits, and other DC voltage regulator circuits. The device is also ideal for use in radio frequency circuits, power amplifiers, and automotive electronics. The flexibility of its adjustment and its compact size make the ER1840-05KP an excellent choice for these applications.The ER1840-05KP uses the concept of electromagnetic induction to work. This concept states that an electrical current will produce a magnetic field in the surrounding environment, and this magnetic field will in turn cause an electric current to flow in a nearby circuit. The presence of the ferrite core in the ER1840-05KP helps control the amount of inductance and the strength of the magnetic field.When this device is connected to a circuit, an alternating current will flow through it. This alternating current will cause the magnetic field to cycle at the frequency of the current. For every cycle of the magnetic field, an equal and opposite electric current is produced, which acts as the inductor’s output. The inductance of the device is determined by the relationship between the winding and the magnetic field.The ER1840-05KP is an efficient and affordable fixed inductor with excellent performance and stability. It has a wide range of inductance values that make it suitable for a variety of different applications. This device is highly versatile and can be used in a number of different electronic circuitry, including those requiring high levels of power efficiency.
