Fixed Inductors

Inductors are basic components of electronic circuits, in their most basic form constructed of a coil of wire. They have the ability to store energy in the form of a magnetic field when current is applied.

One such type of inductor is the IMS02ST2R7K fixed inductor. It is a low-cost, high-performance inductor that is particularly suitable for circuit designs which require high power levels and current flows. The IMS02ST2R7K has a certain variation, the IMS02ST2R2K, which has a higher current rated capacity, making it more suitable for even higher power circuits.

Application Field:

The IMS02ST2R7K fixed inductor is best suited for high power switching applications, where operating conditions involve rapid switch-on/off rates, high frequencies, and higher currents. It is ideal for use in power factor correction (PFC) and dc-ac converters. It can also be used in resonant converters, switched-mode power supplies, LCD and LED backlighting systems, high-speed DC-link capacitors, and telecommunications power supplies.

The IMS02ST2R7K fixed inductor has been designed to offer excellent thermal stability, ripple current capabilities, and a high saturation current. Its inductance value remains consistent from temperature changes, and in most cases suitable for pulse applications with very high inrush currents.

Working Principle:

As mentioned, the IMS02ST2R7K fixed inductor is a type of inductor, meaning it is designed to oppose any change of current in a circuit. It does this by creating a magnetic field surrounding its coil, which when current passes through it stores energy which results in a voltage induced in the coil. This voltage opposes the current, eventually reducing it until it reaches the desired level.

When a different current is required, the induced voltage generated by the IMS02ST2R7K inductor works to raise the current to the desired level. This is done by allowing the energy stored in the magnetic field to be slowly released. Once the desired current is reached, the induced voltage stops producing and current will remain at the desired level.

The IMS02ST2R7K fixed inductor is also considered an active component, which means it can control the output current even when there are varying conditions such as high frequencies and wide pulse duty cycles. This is made possible due to its excellent thermal stability, ripple current capabilities, and high saturation current.
