Fixed Inductors

Fixed inductors are incredibly versatile components in the realm of electronics and engineering. As their name suggests, their inductance remains unchanged regardless of the current, frequency, or temperature passing through them. This makes them an ideal choice for applications where there is need for a precise amount of inductance.

One of the most common types of fixed inductors is the 0819R-38H. This type of inductor is a surface mount device (SMD) that is closely related to the other SMTs, such as resistors and capacitors. It has a nice cylindrical shape with twin leads, which permits easy mounting and handling.

Application Field and Working Principle

The 0819R-38H inductor can be used in a variety of applications, including consumer electronics, smart meters, and industrial automation. It is also useful as an energy storage element due to its high inductance and low dissipation factors.

At its core, the 0819R-38H is an electro-mechanical component. It functions precisely by converting electrical energy into magnetic energy. Whenever a current passes through the device, it induces a magnetic field around the coil. This magnetic field then induces an electromotive force (EMF) in the opposite direction.

The EMF is then transferred to a secondary coil, which results in an inductive effect. In this way, the relationship between the primary and the secondary coil is maintained, and the inductance remains constant. The fact that the inductance of the 0819R-38H remains constant regardless of the current, frequency, or temperature, makes it a perfect choice for multiple regulations, stabilizers, and filters for a wide range of applications.

The 0819R-38H also has excellent thermal characteristics, thanks to its advanced encapsulated design. This means it’s able to handle high temperatures when performing inductive loads without compromising its performance. It also features high corrosion resistance and a wide range of inductance values, allowing it to be used for both high-frequency and low-frequency circuits.

In conclusion, the 0819R-38H is a versatile inductor device that can be used in multiple areas of engineering. It is characterized by its excellent stability, high inductance, and excellent thermal characteristics. This makes it an ideal choice for a variety of applications, from consumer electronics to smart meters.
