Fixed Inductors

A fixed inductor is a type of passive component in electronic equipment. It is used to increase and control the energy flow from one part of an electrical circuit to another.The most common type of fixed inductor is the air core, which consists of a coil of thin, insulated wire inside a non-conductive housing. The principle behind fixed inductors is based on the fact that a current-carrying wire will generate a magnetic field around it. By changing the number of turns in the coil, or the size of the core, this magnetic field can be manipulated to achieve the desired effect.

PTKM100-40SM Application Field and Working Principle

The PTKM100-40SM fixed inductor is a device primarily used in power conversion equipment such as power supplies. It is designed to absorb, store, and release energy as it passes through a circuit. The energy is released in the form of a magnetic field, which can be used to convert the AC current into DC current. The device is capable of handling currents up to 6.4A with an inductance of 8.3 mH

The working principle behind the device is based on Faraday\'s law of induction, which states that an electric current passing through a conductor will cause a magnetic field to be created. In the case of a fixed inductor, the magnetic field created is used to slow down the current passing through it by creating a counter voltage. This voltage is proportional to the rate of change of the current in the inductor.

When the voltage reaches a certain level, the current passing through the inductor will be reduced, allowing for controlled current flow. This is why the PTKM100-40SM is so often used in power conversion circuits. It helps to regulate and stabilize the current and can even dampen out transient voltage spikes.

The PTKM100-40SM provides excellent performance in terms of energy storage and conversion. It can handle currents up to 6.4A, with an inductance of 8.3 mH. The device also features a high current density, with a maximum operating temperature of +150 °C. Furthermore, the inductor is resistant to temperature changes, and its efficiency is significantly higher than other types of inductors.

The PTKM100-40SM fixed inductor is a cost-effective and reliable component that offers a versatile solution for power supply and energy conversion applications. Its high current handling capacity, combined with its response speed, makes it an ideal choice for applications involving high power, such as battery chargers and power supplies.
