Fixed Inductors are electrical devices that are designed to provide inductance in a circuit. The LB3218T220KV is one such device which is utilized for a wide range of applications. It is particularly well suited for high power applications due to its low DC resistance and robust construction.

The LB3218T220KV is designed as a radial leaded inductor and offers a wide range of customizations. It is available in both two and three terminal configurations with a variety of inductance values ranging from 110nH to 60mH. It is primarily used in power converters, DC/DC converters, and servo-motor controllers.

As for its technical specifications, it is rated at an operating temperature range of 0° to 120°C, with a resistance value from 0.007 ohms to 0.15 ohms. Additionally, it features basic insulation, a ripple current rating of up to 14.1A, and an operating frequency range of up to 300kHz. Its rated power dissipation is 30.8W and it supports both AC and DC current.

The LB3218T220KV is constructed of a ceramic core, aluminum alloy case, and ceramic coating. The core is designed to provide enhanced energy storage capabilities, a low DC current, and high AC current. Additionally, it utilizes zig zag inductor technology which helps to reduce the amount of noise in the application. The aluminum alloy casing provides robust protection for both the core and the ceramic coating. The ceramics coating inside the case is designed to optimize heat dissipation which is beneficial for high power applications.

The working principle of the LB3218T220KV is fairly simple. It contains a core which is wrapped in coils. When current passes through the coils, magnetic energy is created which induces an electromagnetic field. This field, in turn, creates a voltage drop which can be used to manipulate the current. By varying the number of coils and the direction of the current, a wide range of inductance values can be achieved.

In conclusion, the LB3218T220KV is a radial-leaded inductor which is designed for use in power converters, DC/DC converters, and servo-motor controllers. It offers a broad range of inductance values ranging from 110nH to 60mH and is designed to withstand operating temperatures up to 120◦C. It has a low DC resistance value and utilizes the zig zag inductor technology to reduce noise in the application. The LB3218T220KV is an ideal choice for high power applications due to its robust construction and efficient heat dissipation capabilities.
