Fixed Inductors

Fixed inductors are a class of electronic components used to store electrical energy in the form of magnetism. They can also be used to produce a varying current, and are used in a variety of applications, including noise filtering and power supply regulation.

PL8133 is a type of fixed inductor. It is a leaded power inductor which provides high power handling and low profile packages for space-constrained applications. It targets power supply, converter, and switch-mode power supplies (SMPS) designs with up to 500Vdc or 800Vdc operating voltage.

The working principle for a fixed inductor is based upon the law of electromagnetism, which states that a current flowing through a wire produces a magnetic field. When the current flow is constant, the magnetic field created has a fixed polarity (i.e. the same direction of polarisation). When the current flow is disturbed, it creates a varying magnetic flux which expands and contracts in order to oppose the disturbance. This opposing force is what creates the inductance.

PL8133 features a high rated current of 3.5A and 6A. It also has a low DCR, which allows for greater power efficiency and reliability. The inductor also has low stray magnetic fields with maximum 30mT or 40mT, for noise reduction. In addition, it also has high thermal couple efficiency for excellent thermal performance as well as a 2-layer substrate for superior chip protection and for optimal noise suppression.

The applications for PL8133 are varied, such as in DC/DC converters, UPS systems, switching power supplies, active PFC circuits, and general-purpose filtering. In addition, it is also suitable for medical device and telecommunications applications due to its high dielectric insulation and radiation-tolerant ceramic lead frames.

PL8133 fixed inductor is an ideal choice for power supply designs with up to 500Vdc or 800Vdc operating voltage and applications demanding high power, low profile, and low radiation. Its use of the law of electromagnetism gives it the ability to create a varying current, as well as storage of electrical energy in the form of magnetism.
