Fixed Inductors

Fixed inductors are used in electric circuits for a variety of purposes. From suppressing electrical noise along with providing precise signal timing to transmitting and receiving radio frequency signals from wireless devices, fixed inductors are extremely useful in a variety of applications. This article will discuss the application field and working principle of the 1638R-16J inductor.

Application Field

The 1638R-16J fixed inductor is specifically designed for switching power supplies, voltage regulators, digital power, and SMPS. Additionally, it can also be used in signal processing and audio system applications. It features a high inductance density and low DC resistance. This makes it especially suitable for low-noise switching power supplies. Other applications for the 1638R-16J include in power filters, uninterruptible power supplies, high-temperature low-noise inductors, and class-D audio amplifiers.

The 1638R-16J also has a relatively low core loss, making it suitable for high-temperature operation. It also has a low DCR, which provides maximum efficiency and allows for better high-current operation. The 1638R-16J also has an excellent temperature coefficient over a wide range.

Working Principle

The working principle of the 1638R-16J fixed inductor is simple. It is basically composed of a coil of wire, which is wound into a fixed rectangular volume and placed within a core of a magnetic material. When a current passes through the coil, it creates a varying magnetic flux that induces a voltage within the coil. This voltage is generated due to the changing magnetic flux, also known as Faraday\'s Law. The generated voltage then induces a counter-voltage in the opposite direction, which creates a counter-current to push against the original current.

The 1638R-16J inductor also has an internal core, which helps to protect the coil from external effects. This is key for applications such as switches, power supplies, and voltage regulators, where the inductor needs to be able to consistently generate a voltage for a given current. The core also helps to stabilize the current, which is important for applications like low-noise switching power supplies.

In short, the 1638R-16J fixed inductor is designed for applications that require high inductance density, low DC resistance, low core loss, and low temperature coefficient. It can be used in a variety of applications, such as power filters, uninterruptible power supplies, high-temperature low-noise inductors, and class-D audio amplifiers. Furthermore, the 1638R-16J inductor works on the same basic principle as all other fixed inductors, which is the creation of a voltage using the changing magnetic flux.
