Fixed inductors, also known as pre-manufactured inductors, are passive components that are limited in their ability to store energy due to the lack of a power grid or other source of energy. The 22R155MC is an example of a fixed inductor that is used in a variety of applications. This article will discuss the application field of 22R155MC, its working principle, and its advantages and disadvantages.

Application field of 22R155MC

The 22R155MC fixed inductor is a popular choice for a wide range of electronics applications, from high-power controllers to low-noise circuits. Some of the most common applications include:

• Filtering: The 22R155MC can be used to filter a wide range of signals, from audio to RF, in order to reduce unwanted noise in a given circuit. The inductor\'s high Q value adds stability to the filter and prevents oscillation.
• Power Supply Decoupling: The 22R155MC is often used in power supply decoupling circuits to reduce the effects of noise and ripple voltage.
• RF Circuits: The 22R155MC is an ideal component for use in RF circuits, such as amplifiers, couplers, and oscillators, due to its low self-resonance frequency, high reliability, and excellent linearity.
• DC/DC Converters: The 22R155MC is an essential component for high-efficiency DC/DC converters due to its ability to control current flowing through the inductor. This helps reduce power losses.

Working principle of 22R155MC

The 22R155MC fixed inductor is composed of a coil of wire and a magnetic core, usually made from a ferromagnetic material like iron or iron alloy. When an electric current runs through the coil, it creates an electromagnetic field around the coil. This electromagnetic field causes a force to be applied to the nearby magnetic core, which can then be used to induce a voltage in the coil or store energy.

Advantages of 22R155MC

• High-Q value: The 22R155MC has a high Q-value of more than 20, giving it excellent filtering and stability characteristics.
• High power handling: The 22R155MC has a high power handling capacity of up to 5A, making it suitable for a range of power applications.
• Wide Frequency Range: The 22R155MC is capable of operating over a wide frequency range, from 0.1MHz to 30MHz, with minimal distortion.

Disadvantages of 22R155MC

• Size: The 22R155MC is relatively large compared to other fixed inductors, making it difficult to integrate into some designs.
• Heat Dissipation: The 22R155MC is not known for its heat dissipation capability, meaning it has to be paired with a heat sink if used in high-power applications.
• Inductance: The 22R155MC is limited in the range of inductance values it can offer, so it may not be suitable for certain designs that require very specific inductance values.

The 22R155MC fixed inductor is a versatile component with a variety of application fields. It has a number of advantages such as high Q-value and power handling, but it also has some drawbacks such as its size and poor heat dissipation. Regardless, the 22R155MC should still be considered for use in many applications due to its wide frequency range and high reliability.
