MDMK2020TR47MM

Fixed Inductors

A fixed inductor, such as the MDMK2020TR47MM, is an electronic component used to provide a controlled amount of induction in a circuit. In a fixed inductor, the inductance is measured in Henries and is fixed – or unchanging – due to being wound onto a non-adjustable core or form. Fixed inductors are primarily used in DC or low frequency AC circuits.

Types of Fixed Inductors

The most common type of fixed inductor is a cylindrically wound inductor, in which the conductor is wound in circular loops of wire around a center core. Other forms of fixed inductors include flat winding tape, planar spiral, monostable, and adjustable inductor. The MDMK2020TR47MM utilizes a cylindrically wound inductor.

Applications of the MDMK2020TR47MM

The MDMK2020TR47MM fixed inductor is a particularly useful component in many applications, including filtering, coupling, power factor correction, and storage in switching mode power supplies and active power factor correction. It is also commonly found in RF/microwave circuits, used for reactive matching, building bridges, and antenna matching.

Working Principle of the MDMK2020TR47MM

An inductor works by storing energy as a magnetic field when an electric current passes through it. This phenomenon was first observed by Michael Faraday in the early 1800s. This magnetic field then interacts with the current in the circuit, providing inductance. The greater the number of turns of a coil, the greater the inductance. The MDMK2020TR47MM is designed to provide a specific and controlled amount of inductance.

Given that inductors are passive components that store energy in a magnetic field, they are not designed to create power. Instead, their advantage lies in their ability to exceptionally filter signals and reduce power losses. The MDMK2020TR47MM, for example, can be specifically tailored by its number of turns to respond to a desired frequency. It is also ideal for situations in which an exact inductance must be achieved, such as a switched-mode power supply.

Conclusion

The MDMK2020TR47MM is a high quality, cylindrically wound, fixed inductor that is designed to provide a consistent and controlled inductance. It is suitable for a wide range of applications that require exact inductance and power losses that don’t alter the signal. The MDMK2020TR47MM is a reliable and effective component in many electrical circuits.
