Fixed inductors are electronic components that produce an inductance value that does not change when electric current is applied. This is in contrast to variable inductors, whose values can change with the input current. At their core, inductors are coils of magnetically conducting materials, such as copper or iron, through which electricity flows. Inductors are essential in power supplies, radio transmitters, and in many other applications. The SC32B-151 is a type of fixed inductor that has a wide range of applications in circuit design and is favored among many engineers.

Applications

The SC32B-151 is an especially popular inductor for power electronics and switching circuits due to its high power efficiency and low heat generation. With its high saturation and low resistance, it is well suited for energy-democratic applications like inverters, controllers, voltage regulators, and delta converters. The SC32B-151 is also well suited to AC and DC drive systems, particularly those for EV/HEVm electric vehicles, robotic systems, and industrial-grade equipment. Its stable inductance values make it well suited for use in PFC (power factor correction) converters, DC-DC converters, CRT displays, drivers, and other components in small electronic devices.

Working Principle

The SC32B-151’s fixed inductor utilizes a number of windings or coils to produce an electric current. As electricity flows through the windings, it creates a magnetic field that inducts a voltage that is related to the magnitude and intensity of the current. Since the inductor has no moving parts, energy is not lost as it flows through the windings. The efficiency of the inductor is determined by the number and size of windings, which in turn is determined by the amount of current to be produced and the intended applications.

The magnetic field created by the windings of the fixed inductor determines both its inductance and its current handling ability. The current handling power of an inductor is directly related to its inductance. The higher the inductance, the greater the current handling ability – up to a point. If an inductor’s inductance is too high, the current flowing through it can become too great, leading to overheating and eventual damage.

In order to protect the SC32B-151 from damage from excessive current, most applications will use a protection device. Protection devices work by regulating the current that passes through the windings and preventing excess currents from damaging the components. This is done by sensing the current flow and shutting off the current when the allotted limit is exceed.

Conclusion

The SC32B-151 is a type of fixed inductor that is well-suited to applications in power electronics and switching circuits due to its high power efficiency and low heat generation. Its stable inductance values make it well-suited for use in PFC converters, DC-DC converters, and other components. Though it is relatively low-maintenance and long-lasting, protection devices should be used in applications where it is likely that the current handling capability of the SC32B-151 will be exceeded.
