Fixed Inductors

1812-183H Application Field and Working Principle

Fixed inductors, also known as inductors, are passive electronic components found in virtually all electronic devices today. Even though they don’t produce energy, they still play an important role in the functioning of a device. They act as a force that helps convert energy from one form to another, allowing devices to work more efficiently. The 1812-183H, specifically, is a surface mount type inductor commonly used in power supplies. It also contains a ferrite core material, making it residual radiation-resistant.In terms of its application field, the 1812-183H is often found being used in power supplies in electronic control systems, such as those used in aerospace and military systems. It has also been used in telecom systems, home and commercial security systems, medical devices, video surveillance, video game consoles, and audio/visual devices. With its special design, the 1812-183H is suitable for applications with a higher package density and optimized performance. It also allows for higher current savings and meets the requirements of various compliance standards.In terms of its working principle, the 1812-183H is designed based on a specific technical characteristic. This essentially dictates the amount of inductance that the device has, which in this case is 4.7 μH to 22 μH. The amount of inductance is determined by the number and nature of the windings within the inductor. In other words, the core material and the number and type of windings dictate the range of inductance that the 1812-183H has.The 1812-183H also has a low DC resistance, as well as self-heating characteristics. This is important because inductors are commonly used in power supplies, and there is always the risk that the power will overheat and lead to system failure. With the 1812-183H’s low DC resistance, the risk of self-heating is minimal and the device’s efficiency remains high.The 1812-183H also features a saturated current of 2.4A. This is important because it ensures that the device doesn’t produce too much current at any given time. The device also has an insulation resistance of 100 GΩ, meaning that it provides very good insulation and decreases the risk of electric shock. It also has a temperature range of -55°C to +125°C. This makes the 1812-183H suitable for use in both cold and hot environments.Finally, the1812-183H’s ferrite core material makes it highly resistant to residual radiation, meaning that it can operate reliably even in the presence of residual radiation. This makes it ideal for use in aerospace and military applications, as well as in commercial and medical applications, in which residual radiation may be present.In conclusion, the 1812-183H is a surface mount type inductor that is ideal for use in power supplies, telecom systems, security systems, medical devices, and audio/visual devices, amongst others. Its range of technical characteristics make it suitable for a variety of applications, and its ferrite core material makes it particularly resistant to residual radiation. It is, therefore, an essential device for many complex electronic systems.
