Introduction

Fixed inductors, also known as inductors, are components that store electrical energy in a magnetic field. They are used for switching and filtering in various electronic circuit designs. Fixed inductors have excellent electrical characteristics and can provide current limiting, short-circuit protection, and frequency-dependent signal filtering. IR02SHR68K is a type of fixed inductor with specific characteristics that make it suitable for a variety of applications.

Application Field of IR02SHR68K

IR02SHR68K is a high-performance, low-cost fixed inductor available in various sizes and shapes. It is primarily used in high-frequency applications, such as radio frequency (RF) circuits. IR02SHR68K is also suitable for use as an output inductor in power supplies, as an input inductor in multi-layer filter circuits, and as a coupling inductor in voltage-controlled oscillators (VCOs).

Principles of Operation

The essential element of all inductors is a single or multiple loop of wire. The circuit symbol for IR02SHR68K consists of two arcs connected with a line, which is an indication of the linear inductance in the component. The inductance is measured in henries (H), which is a unit of magnetic flux. The amount of inductance generated by the wire loop depends on the size of the loop, the number of turns of wire, and the structure of the loop. Longer, thinner wire loops have higher inductance than shorter, thicker wire loops. Winding the same wire around a coil form increases the inductance significantly. The magnetic field around the component is proportional to the current through it, and an alternating current generates an alternating magnetic field. This alternating field induces an electromotive force (EMF) which opposes the applied current. The emf produced is proportional to the frequency of the applied current, which explains why inductors are used in frequency-dependent circuits.

Advantages of IR02SHR68K

One of the main advantages of the IR02SHR68K is its low cost compared to other inductors. It is also known for its high-power delivery, low losses, and excellent electrical characteristics. The device is capable of operating over a wide temperature range, from -55°C to +125°C. It also has high current ratings, up to 4A, and its construction is capable of withstanding extreme vibration and shock. Due to its small size, it is suitable for use in high-density circuit designs. In addition, the component comes in a variety of shapes and sizes, from 0.1μH to 10μH. This wide range makes it suitable for a variety of applications, from filtering, coupling, and decoupling, to power line and DC-DC converter applications.
