Fixed Inductors

Fixed inductors, also called fixed inductance coils, are coils with low resistance and high inductance. They consist of a single winding of wire, constructed of ferromagnetic material, that is configured into a specific shape. The shape of the coil contributes to how much inductance the coil has. Typically they are used in radio and television signal pickups, and in frequency-selective circuits such as filters and chokes.

HM66-621R8LFTR13 is a type of fixed inductor manufactured by GALAXY. It is a surface mount FET (Field Effect Transistor) type inductor with a high inductance of 6.21mH (millihenry) and an operating range of -55°C to +125°C. This inductor is a toroid-style construction and has an included lead frame to allow easy soldering. It is particularly suited for use in applications requiring high space efficiency and low loss.

HM66-621R8LFTR13 Working Principle

The HM66-621R8LFTR13 inductor operates by using electromagnetic principles. When a current is passed through a wire wound in a coil shape, it generates a magnetic field. This magnetic field induces a voltage in the surrounding wire. This voltage opposes the flow of current and is proportional to the rate of change of the current. This effect is known as inductance. The inductance of the coil is determined by the number of turns of wire, the type of cores, and the inductor\'s shape.

The HM66-621R8LFTR13 inductor has a high inductance combined with low resistance thanks to its toroidal shape. This shape maximizes magnetic flux due to the close magnetic coupling between turns of wire and provides a low-loss circuit element with a high inductance.

In addition to its shape, the HM66-621R8LFTR13 also features a high-temperature rating and a wide operating range. This makes it suitable for use in a variety of high-power applications. Its small size is also beneficial in reducing current losses in the circuit and allowing a higher power rating.

The HM66-621R8LFTR13 inductor is a versatile and useful component for automotive, electronic, and other applications requiring a reliable and energy-efficient device.
