Fixed inductors are electrical components that store a substantial amount of energy in the form of magnetic fields. Commonly found in consumer electronics, they are most often used to filter out high frequency signals in radios and TVs and to reduce or limit the amount of current in complex circuits. The IR04STR82K is a specific type of fixed inductor, and it is important to understand its application field and working principle in order to maximize its effectiveness.

The IR04STR82K is a surface mount, three terminal fixed inductor. Weighing only 2.2 grams, it is a compact and lightweight component, making it ideal for applications calling for a compact size. It is constructed of composite materials featuring low profile enameled copper wire wound around a high frequency ferrite core. This construction provides superior temperature resistance and high inductance values of 120 micro-henries. The inductance can be tailored to a range of values, allowing for use in a broad range of applications from microcontrollers to power systems.

The application field of the IR04STR82K is diverse, and it finds its use in many segments of the circuit design industry. One of the most common uses of the device is for EMI filtering. EMI, or electromagnetic interference, is a common problem in modern electronic circuits. High frequency signals can cause interference in other nearby circuits, leading to faulty performance or even poor signal reception. By using a fixed inductor such as the IR04STR82K, it is possible to create a low pass filter which helps to reduce the amount of high frequency interference. This inductor can also be used as a voltage regulator for sensitive components, providing a smoothing effect and reducing voltage spikes.

The working principle of the IR04STR82K is relatively simple, but it is important to understand in order to make the most of the component. When current is passed through the device, it creates a magnetic field which stores up energy. This energy is then released back into the circuit when the current is stopped. This principle can be used to regulate and filter out high frequency signals, reducing the amount of interference in a circuit. It can also be used to limit current, providing an efficient and easily tailored solution to this problem.

In conclusion, the IR04STR82K is an efficient and lightweight fixed inductor, boasting excellent temperature resistance and low profile enameled copper wire windings. It is applicable to many different types of circuit designs, ranging from EMI filtering to voltage regulation. Its working principle is comprised of passing current through the component to create a magnetic field for storing up energy, and then releasing it back into the circuit for a smoothing effect or other desirable applications.
