1840-04F Datasheet/PDFFixed inductors are electronic components that store energy in a magnetic field when an electric current passes through it. They are widely used in diverse applications including radio receivers and transmitters, analog to digital converters, and noise filter circuits. An example of a fixed inductor is the 1840-04F, which is a type of axial lead-style inductors that are used for high-frequency and low-frequency filter circuits, low-noise attenuators, and power supply circuits.
The 1840-04F is a through-hole inductor that is composed of ferrite and two coils. It has a rated inductance value of 0.4uH and a rated DC current of 20mA. It also has a low DC resistance of only 0.2Ω. The 1840-04F has excellent frequency characteristics and can handle high power loads due to its use of ferrite material. The inductor has an axial lead style with an operating temperature range of -20°C to 70°C.
The 1840-04F is an ideal component for applications that require high-frequency and low-frequency filter circuits, such as noise filtering in radio and television receivers. It can also be used in power supply circuits to reduce voltage and current ripple, or in attenuators to reduce signal levels. In all cases, the 1840-04F\'s superior frequency characteristics and low DC resistance make it an ideal choice.
The 1840-04F works by storing energy in a magnetic field when an electric current is passed through it. When a current is applied to the inductor, a magnetic field is created that intercepts the current and stores energy, which is then released back into the circuit when the current is interrupted. This process is known as inductance. The inductor\'s size and shape determines the amount of inductance, or the amount of magnetic energy it can store. The inductance of the 1840-04F is determined by its construction of two coils, which creates a greater magnetic field and thus a higher inductance value.
The 1840-04F is ideal for low-noise attenuators, high-frequency and low-frequency filter circuits, and power supply circuits. Its low DC resistance, superior frequency characteristics, and ability to handle high power loads make it an ideal choice for a wide range of applications.
