Fixed Inductors

The SCTH2010-R56 is a fixed inductor with a rated inductance of 10µH. It offers excellent power handling capabilities along with low DCR and high flux density. The part has a wide operating temperature range from -40°C to +105°C. It is suitable for use in a variety of applications that require stable inductance characteristics.

Application Field

Inductors are widely used in various electric and electronic applications. The main applications are switching power supplies, DC-DC converters, DC-AC inverters, electrical filters, power amplifiers and resonant circuits. SCTH2010-R56 inductors are especially suitable for use in low-power switching applications such as portable electronic devices, automotive electronics, and medical equipment.

Working Principle

A fixed inductor works on the principle of self-inductance. Whenever current flows through an inductor, it generates a magnetic field. This magnetic field induces an opposing voltage in the inductor, creating an opposition known as self-inductance. This self-inductance resists changes in the current, and stores energy in the form of the inductor’s magnetic field. Thus, a fixed inductor can be used to filter out the high frequency components of an AC current and to provide an impedance path for high frequency RF signals.

Construction

An SCTH2010-R56 fixed inductor is a cylindrical device composed of a ferrite core, copper windings, and a plastic cover. The core is made of high permeability ferrite material that aids in providing the desired inductance. The copper is wound in a specific manner to ensure that the desired inductance value is obtained. The plastic cover provides protection from mechanical, chemical, and electrostatic damage.

Advantages and Disadvantages

Fixed inductors offer many advantages over other inductor types. They are easily manufactured and highly stable in the presence of temperature and frequency changes. They also have a uniform inductance value that is less vulnerable to temperature and frequency changes. These inductors are highly efficient and provide a low resistance path for the current, allowing for improved power handling capabilities. They are also low-cost and easily available.

The major disadvantage of fixed inductors is that they have fixed inductance values. This means that they are not suitable for use in applications that require adjustable inductance values. They also undergo significant losses when operated at higher frequencies. Additionally, these inductors can produce electromagnetic interference (EMI) when operated at higher frequencies, which can interfere with other electronic systems.
