Fixed Inductors: 0805-68NJ Application Field and Working Principle

Inductors, or coils, are devices used to create inductance in an electrical circuit. Inductance is defined as the ability of a coil or wire to oppose any changes in the current that is flowing through it. This is due to the changing magnetic field around the coil whenever a current is flowing. A fixed inductor, like a 0805-68NJ, is specifically designed to maintain a constant inductance across a wide range of temperatures and frequency applications. This article will discuss 0805-68NJ application field, as well as its working principle.The 0805-68NJ is a surface-mounted device (SMD) that has a four-digit number denoting its physical size on the market. This inductor is one of the most widely used fixed inductors and is often used in applications such as DC-DC converters, switching voltage regulators, power supplies, and general-purpose circuit design. It features a low cost, high reliability, and a wide operating temperature range.Due to its small size, the 0805-68NJ offers several advantages in terms of installation, such as a high degree of space utilization and an improved mechanical strength versus through-hole designs. The 0805-68NJ has a diameter of 8mm, a height of 5mm, and a lead spacing of 0.5mm. This allows it to fit into transistors, integrated circuits, connectors, and other SMD packages, making it the ideal choice for high-density applications.In terms of its working principle, the 0805-68NJ utilizes an iron-core inductor, which is able to create a self-generated magnetic field when a current is applied. This causes a form of inductance, which can be measured in Henries (H). The inductance of a 0805-68NJ is typically around 680nH (nanohms).The 0805-68NJ is a low-loss inductor, meaning that the majority of the current applied to the coil is reduced by the self-generated magnetic field, as opposed to being lost in resistive components. Additionally, the 0805-68NJ is designed to maintain its inductance even when faced with high frequency or high temperature ranges. This makes it useful in applications such as high-frequency switching devices, power supplies, and communications systems.Overall, the 0805-68NJ is an excellent fixed inductor for applications such as DC-DC converters, switching voltage regulators, and power supplies. Its small size, low cost, and broad operating temperature range make it an ideal choice for high-density, high-frequency, and high-temperature designs. Its working principle makes use of an iron-core inductor, which produces a self-generated magnetic field when current is applied. This causes a form of inductance, which can be measured in Henries (H). In general, the 0805-68NJ is an effective choice for any design that requires a constant inductance at high frequencies or high temperatures.
