Fixed inductors refer to the inductors consisting of a single coil and its core, which are manufactured at a certain predetermined inductance. They are typically made from layers of copper wire wound around a ferrite core with insulation between them, thereby they can store energy in the form of alternating current. 0819R-82H is one of the most popular fixed inductors in the design of the circuit. It is mainly used to limit the high-frequency current on the circuit. It is one of the most important components in the short circuit protection, filtering, and feedback applications.

Application Field

0819R-82H fixed inductor is used in automotive applications, power management, and consumer electronics. Automotive applications include electric power steering, active suspension, and engine control systems. In power management applications, the inductor is used for switch-mode power supplies and snubbers, and is frequently used in consumer electronics, such as power adapters and battery management systems.

Working Principle

The 0819R-82H Fixed Inductor works by effectively forming a magnetic field around the core, when an electric current passes through it. It can be considered as a device that stores the energy of the current, similarly to a battery. When the current is stopped, the inductor will release the stored energy slowly, so reducing the current in the circuit. As a result, the inductor helps to reduce overloads in electrical circuits, preventing them from shorting out. It also helps to dampen fluctuation caused by voltage surges.

The 0819R-82H can safely handle the over-rated current to prevent short-circuits and maintains a stable current over a range of voltage levels. It also offers superior surge current capability, thermal temperature rise, and enhanced temperature stability, making it especially suitable for automotive, power management, and consumer electronics application.

In the automotive application, the 0819R-82H helps to reduce power dissipation by significantly reducing the total voltage ripple. This improves power efficiency and durability of the system. The inductor helps to reduce noise and increases the life of the system because it resists changes in temperature or load. It also prevents the system from malfunctioning during high-load conditions.

Conclusion

The 0819R-82H fixed inductor is widely used in many different applications. Its ability to store energy when a current passes through it and its excellent surge current capability, thermal temperature rise and temperature stability make it an ideal choice for various automotive, power management, and consumer electronics applications. Its robust design enables it to withstand a range of conditions and prevent system disruption, thus ensuring reliable operation and longevity.
