Fixed Inductors

Inductors are essential electrical components found in most electronic devices. They are used to store energy in the form of a magnetic field and then convert the energy back into an electrical current. Fixed inductors are an important type of inductor that have a fixed inductance value and are designed to carry a specific current when operating correctly. One example of a fixed inductor is the PT12128SL, which can be used in a variety of applications.

PT12128SL Application Field

The PT12128 SL fixed inductor is a 0.127 mm thick, 12.9mm square inductor designed primarily for high current filtering applications. It has a rated inductance of 1.2μH and is capable of handling up to 3A of current continuously. Additionally, it is able to dissipate up to 5W of power safely, making it ideal for high current applications such as DC-DC converters. It is also widely used for anti-aliasing filters in audio applications, as well as other power line applications.

PT12128SL Working Principle

At its most basic, the PT12128SL fixed inductor works by storing and releasing an electric current with an induced electromotive force (EMF). This EMF is generated when a changing magnetic field passes through an inductor, which causes a current to be generated in the inductor. As the current passes through the inductor, a magnetic field is created that acts against the induced EMF, resisting the flow of current. In essence, the inductor works to store and release energy in the form of electrical current.

The PT12128SL also uses self-shielding technology. This is a type of shielding that uses the self-inductance of the inductor to keep outside elements from interfering with the inductor’s operation. This helps to ensure that the inductor remains stable and operates correctly.

Conclusion

The PT12128SL fixed inductor is a versatile component that can be used in many high-current applications. It has a rated inductance of 1.2μH, and is capable of handling up to 3A of current continuously and safely dissipating up to 5W of heat. Additionally, it features self-shielding technology to help ensure that the inductor remains stable and operates correctly. With its wide range of applications and impressive specs, the PT12128SL is an excellent choice for high-current filtering and other power line applications.
