Fixed Inductors

The CDRH74-821MC is a type of fixed inductor used in a variety of electrical and electronic applications. It is a non-polarized inductor with an inner core and a winding, which makes it ideal for use in power, lighting, and telecommunications applications. Fixed inductors are commonly used to provide a stored energy reserve that can help maintain voltage levels and current flow in circuits.The CDRH74-821MC has a black, ferrite core and a winding of enamelled copper wire. The inductance of the device is determined by the number of turns in its winding and is usually specified in Henrys (H). The higher the rating, the higher the current-handling capacity it provides. The maximum voltage rating of the inductor is dependent on the wire gauge used to make the winding.The CDRH74-821MC is designed for peak current ratings up to 3.0A (at temperatures up to 70°C). Its also has excellent electrical and mechanical performance. Its electrical characteristics include an inductance of 800mH ± 20% and a DCR of 0.150Ω ± 10%. As for its mechanical characteristics, the CDRH74-821MC has a ripple waveform of <30mV, an outside diameter of 9.9mm, and a maximum operating temperature of +100°C.The CDRH74-821MC’s working principle is simple. It stores energy in its magnetic field, which helps to control the current and voltage levels in a circuit. When an electric current flows through the inductor, a magnetic field is generated around the inductor. This magnetic field stores the energy from the current, and then releases it into the circuit as the current changes direction. As the amount of current flowing through the inductor changes, the magnetic field adjusts accordingly, enabling the inductor to maintain a steady current level in the circuit.Fixed inductors are used in a variety of applications, such as power circuits, telecommunications, and industrial control systems. They are often used to filter out electromagnetic interference or to limit inrush currents. Fixed inductors are also used to reduce transient voltages, to store energy, or to provide a universally constant voltage.The CDRH74-821MC is an ideal choice for applications that require an inductor that can handle high currents. Its high-quality construction, durable design, and excellent electrical and mechanical specifications make it an excellent choice for a variety of applications.
