Fixed Inductors

Fixed inductors, also known as chokes, are electronic components built mainly of a coil of a wire that stores energy or generates a magnetic field. Fixed inductors are widely used in electrical and electronic circuits for several purposes, such as filtering, regulating current, providing immunity from interference, setting oscillator frequencies, providing high current at low voltages and filtering signals from unwanted AC components. The most common type of fixed inductor is the SC104-680, which is a small, cylindrical device with a threaded core.

Application Field

The SC104-680 is designed primarily for low-frequency applications, such as noise reduction, power factor correction, DC/DC converters, voltage multipliers, switching regulators, power supplies and audio amplifiers, as well as medium and high-frequency applications.

The SC104-680 is used in wide range of applications. It can be found in automotive electronics, electronic test equipment, LED drivers, telecom systems, computers, and industrial controls. It is used in switching power supplies, step-up voltage converters and boost converters, and other diode or transformer-based circuits for energy saving. The SC104-680 is also suitable for radio-frequency, LED drivers, audio and switching power filters and ray detectors.

Working Principle

The SC104-680 inductor functions mainly by creating an electro-magnetic field around its core. When an alternating current is applied to the inductor, the coils of wire generate a magnetic field with a North Pole and a South Pole. This magnetic field quickly collapses and the energy stored in the field is released in the form of an alternating current. This phenomenon is known as the inductive reactance, and it is the basic principle of the SC104-680 inductor.

The alternating current flowing through the device is kept at a constant amplitude and frequency by the action of the inductance and capacitance. The capacitance of the device is set by the size of the core and the nature of the windings. The capacitance of the core is determined by the core\'s ability to store electrical energy. The inductance of the device is determined by the number of turns in the windings.

The SC104-680 can also be used in power supply applications, such as in topologies like Buck, Boost or Flyback converters. In these applications, the inductor is used to control the speed and efficiency of the converter.

The SC104-680 is also extensively used in a variety of electronic circuits due to its long life and dependable performance. It is a highly efficient inductor with a low equivalent series resistance, and it is able to handle high currents with ease. Its compact form factor ensures that it takes up minimal space in the printed circuit board.

The SC104-680 is a robust and reliable inductor that is designed to last for a long time. Its reliability is further ensured by its high-temperature insulation for greater protection in harsh environments. The inductance value is stable between -50°C and +85°C with a temperature coefficient of +/-10%.
