Fixed Inductors

An inductor is a passive device that can store energy in a magnetic field, and is used in various types of electronics ranging from integrated circuits, power supplies, and sound systems. One type of inductor is the fixed inductor, which consists of a tightly wound coil of wire around a core of either air or semiconducting material. It stores energy through the inductance of the electric current passing through the wire within the magnet.

The 0819R-34H fixed inductor is a device commonly used in the telecommunications and consumer electronic industries. It has a footprint of 8.0mm x 8.0mm and a height of 3.7mm. The 0819R-34H has an inductance range of 2.2~10 µH, a current rating of up to 10A, a saturation current up to 60A and a DC resistance from 0.07ohm.

The 0819R-34H can be used in various applications such as DC/DC converter, switching power supplies, battery chargers, and mobile phone chargers. It is also suitable for high switching speed circuit and high surge current circuits, such as PFC circuits, and it is ideal for resonant applications. The 0819R-34H has a low profile, which makes it ideal for board space-constrained applications.

The working principle of the 0819R-34H fixed inductor is based on the principle of electromagnetic induction. When a DC current is passed through the inductor, a magnetic field is created. This current then increases the magnetic field, which produces a voltage across the inductor. This voltage opposes the increase of the current, and the inductor acts as an opposition to changes in the current in the circuit, thus allowing it to regulate the flow of current.

The 0819R-34H fixed inductor is an affordable yet reliable device that can be used in a variety of applications. Its low profile makes it ideal for board space-constrained applications, and its high current and inductance ratings make it suitable for high switching speed circuits. It is also built to withstand high surge currents, making it an ideal choice for DC/DC converter and PFC circuits. And since the device is relatively small in size, it can also be used in portable electronics, such as mobile phones, and other small form-factor applications.
