Fixed Inductors

Fixed inductors, also known as non-adjustable inductors, are electrical components that store energy in the form of a magnetic field. They are similar to coils of wire, but instead of oscillating with current, they resist the buildup of charges and create a magnetic field. A P1812-103J fixed inductor is a type of fixed inductor used in a variety of power electronics applications.The P1812-103J has a rated inductance of 0.103mH and an operating temperature range from -25°C to +125°C. Its core material is ferrite and its construction features tight tolerances on inductance and temperature. Additionally, the P1812-103J is available in four packages: axial-leaded, surface-mount, over-molded, and vacuum-molded.Due to its small size, low DC resistance, and superior frequency response, the P1812-103J is suitable for a wide range of applications. It can be used as an inductor in DC-to-DC converters, as a filter inductor for switching power supplies, and in circuit applications such as signal conditioning, lossless current sensing, and in RFI filtering. It is also used in telecommunication systems such as mobile phones.The working principle of the P1812-103J fixed inductor is based on Faraday\'s Law of Electromagnetic Induction. When an electric current passes through the component, it induces a magnetic field around it. As the current varies with time, the magnetic field varies as well. This changing magnetic field in turn induces an electrical current flow in the opposite direction, with the same magnitude. This is known as the negative back-emf effect.The induced current in the P1812-103J creates an opposing force against the original current, in effect limiting its amplitude. This limiting effect is how the inductor works to control and shape the electrical signal. Since the inductor offers high impedance to DC currents, it acts as a filter, allowing only AC signals to pass through. This prevents any DC components from affecting the overall signal.In summary, the P1812-103J fixed inductor is a versatile component that can be used in a variety of applications to control and shape electrical signals. Its broad operating temperature range, small size, low DC resistance, and superior frequency response make it a suitable choice for a variety of power electronics applications.
