Fixed Inductors

Fixed inductors, also known as coils, chokes or reactors, are passive components consisting of a wire wound around a core, designed to introduce inductance to an electronic circuit. The PTKM250-50SM is a fixed inductor and is designed for use in a variety of electronic applications. This article will discuss the application field and working principle of this particular product.

Application Field

The PTKM250-50SM fixed inductor is designed for use in a few key areas. These include:

• Audio Frequency (AF) applications
• Radio Frequency (RF) applications
• Power Supply applications
• Signal Processing applications
• Computer and Telecommunications applications

Due to its small size and light weight, the PTKM250-50SM inductor is particularly suited for use in mobile and embedded products.

Working Principle

An inductor works by introducing inductance into a circuit. Inductance is the ability of a coil of wire to store energy in the form of a magnetic field. When an electrical current moves through the PTKM250-50SM fixed inductor, it causes a magnetic field to be created within the inductor. This magnetic field stores electrical energy which can be subsequently used by the circuit.

The amount of inductance the PTKM250-50SM offers is indicated by a value known as the inductance coefficient (L). This value is measured in henrys. The higher the L value, the greater the inductance offered by the component. The typical value of L for the PTKM250-50SM is 250µH.

Inductors can also be used as a ‘choke’ in a circuit. This is a type of filter which is used to limit the flow of AC current, but allow DC to pass through. By utilizing the PTKM250-50SM as a choke, it is possible to reduce the amount of interference caused by electrical noise in a circuit.

Conclusion

The PTKM250-50SM fixed inductor is a popular choice for a number of key applications due to its small size and high frequency response. It is also suitable for use as a choke, allowing it to be used to reduce interference in a circuit. This article has discussed the application field and working principle of this particular product.
