Fixed inductors, also known as fixed coils, are components of an electrical circuit that are used to store energy in the form of magnetic fields. They are composed of an inductive coil, two electrical leads and a casing. The inductor is a passive device used to control the current flow in a circuit. Fixed inductors are used in a wide variety of electrical applications such as filters, amplifiers, motors, relays, switches and other control circuits.2256-21K is a type of fixed inductor manufactured by Walsin Technology, a global leader in the production of numerous types of fixed inductors. 2256-21K fixed inductors have a wide range of application fields, including general electronics and radio frequency (RF) systems, automotive applications, medical equipment and instrumentation, audio systems, power supply systems, computer peripherals, and telecommunications and networking systems.2256-21K fixed inductors are designed for use in high currents and/or high voltage applications. They feature a low profile, small size and high power capability, making them ideal for space-constrained applications. The inductors have an operating temperature range from -40°C to +105°C and are highly reliable with a long usable life. The inductors are available in various package types such as SMD, SMT, DIP, wire wound and more.The working principle of a fixed inductor includes the buildup of a magnetic field when an electric current is applied to it. When the current is increased, more of the energy is stored in the magnetic field. As the current is decreased, the stored energy is released in the form of an induced voltage. This induced voltage is then effectively used in the intended circuit. This is how fixed inductors regulate the current in an electrical circuit and prevent it from exceeding its maximum value.In addition to controlling the current flow, fixed inductors can also provide impedance to the circuit. This impedance is determined by the inductor’s physical characteristics such as its geometry and the size of its coils. This allows the circuit to block external signals and act as a filter, preventing interference from reaching the circuit and affecting it in a negative manner.Fixed inductors are widely used in various applications due to their simple design and their ability to regulate current flow and provide impedance. 2256-21K fixed inductors from Walsin Technology are specially designed for high power rating applications that require a low profile and small size. The inductors are reliable and easy to use, making them an ideal choice for a variety of different applications.
