Fixed Inductors

Inductors are essential components of any electrical system and are used for a variety of purposes. This article will focus on the ELL-CTV821M, a fixed inductor manufactured for use in automotive applications. We will look at the application field of the ELL-CTV821M and its working principle.

Application Field

The ELL-CTV821M is a fixed inductor specifically designed for automotive use, making it suitable for applications such as ignition, power conversion, and control systems. It is also suitable for use in general, commercial, and industrial applications. This inductor features an inductance with a maximum value of 0.8 mH and a rated current of 1.5 A.The ELL-CTV821M is especially suitable for sparking application due to its low profile, making it suitable for space-constrained areas. It also features an excellent DC resistance, making it ideal for current sensing applications.

Working Principle

The ELL-CTV821M works on the principle of electromagnetic induction. When a current is applied to its windings, a magnetic field is generated within the inductor. This magnetic field then induces a magnetic flux in the air surrounding the inductor. The flux then creates an opposing voltage in the inductor, which is known as the back EMF. The back EMF can be used to control the flow of current in the circuit. For example, the inductor can be used to limit the current flowing through the circuit by reducing the magnetic field generated by the inductor. This is known as inductive reactance and is particularly useful in applications such as motor control circuits.

Conclusion

The ELL-CTV821M is a fixed inductor designed specifically for automotive applications. It features an excellent inductance value and DC resistance, making it suitable for use in ignition, power conversion, and control systems. Its low profile makes it suitable for sparking applications and its inductive reactance makes it ideal for motor control circuits.
