Fixed Inductors are passive electronic components that are widely used to store energy in the form of a magnetic field. The SPD125-184M is a fixed inductor designed for a variety of applications, including the DC/DC converters, DC motor control, switching power supplies, and printed circuit boards.

The inductor’s design consists of an iron powder core surrounded by a plastic housing and several copper wires wrapped around the iron powder core. The copper windings are insulated and designed to create a strong inductive field. The inductance of the SPD125-184M ranges from 0.1µH to 10uH, depending on the number of turn on the copper windings. A simple formula can be used to calculate the inductance of any fixed inductor, which is:

Inductance (µH) = turn-length x total-turn/1000

The core material used in the inductor can significantly affect its inductance. The iron powder core used in the SPD125-184M allows for a wide range of inductance values and higher current ratings than those achieved with other types of cores. The SPD125-184M also has a high saturation current rating with a maximum of up to 10A. It also features a high Q factor that is typically greater than 95 at 10MHz, which allows for good power transfer efficiency. The inductor also has a high temperature range of -40° to +125°C and can operate up to a maximum temperature of +150°C with lower saturation current ratings.

The SPD125-184M is commonly used in AC and DC to DC power conversion systems, such as in buck converters. In these applications, the SPD125-184M is used to convert the supply current into a stepped down current signal to feed other components in the circuit, such as a resistor or capacitor. This type of inductor can also be used in DC motor control applications, where its constant inductance helps to regulate the current into the motor. It can also be used in switching power supplies, such as those found in personal computers.

The SPD125-184M is also widely used in printed circuit boards, where it helps to reduce electrical interference and noise generated by the circuit components. The inductor acts as a filter, absorbing much of the high-frequency noise coming from the circuit. To achieve this, the inductor is placed close to the sources of the noise and the circuit is carefully designed to ensure maximum effectiveness.

The SPD125-184M fixed inductor is a high-performance and reliable component for a variety of applications. Its flexibility and wide range of inductance values make it an ideal choice for power conversion systems, DC motor control, and printed circuit boards. With its high saturation current rating and temperature range, the SPD125-184M is a reliable choice for a variety of applications.
