Fixed Inductors: LQH43NN5R6K03L Application Field and Working Principle

Fixed Inductors are electric components that have a fixed inductance value. They are widely used in many applications that require a constant level of inductance. Furthermore, these components are used in power supplies and communications equipment. The LQH43NN5R6K03L, manufactured by Murata Manufacturing Co., Ltd, is a fixed inductor that exhibits superior heat resistance and flip chip mounting properties. This inductor is typically used for d.c – d.c converters and power supplies. The maximum rated voltage for this device is 16V, with a rated current of 4.2A. Its inductance value lies in the range of 3.3 – 3.9 mH.The working principle of the LQH43NN5R6K03L is quite straightforward. In essence, the device induces a voltage in a coil due to the current passing through the winding. This induced current is proportional to the current, and also depends on the number of turns in the inductor’s winding. This is the basic principle behind the working of an inductor. The LQH43NN5R6K03L is constructed using high-grade ferrite cores, and its body is made from ceramic. The ceramic body is coated with a layer of silver plated or nickel plated copper that acts as an electrical conductor for the device. The ceramic body is heat-resistant, which allows the device to perform in extreme temperatures. Furthermore, the body of the inductor features a metal cover to ensure its robustness in corrosive environments. The inductor’s flip chip mounting feature aids in the efficient transfer of heat during operation. This feature helps reduce the inductor’s temperature rise, which in turn extends its life. Furthermore, this feature helps reduce the inductor’s size and weight, making it easier to install in a circuit. In conclusion, the LQH43NN5R6K03L is an extremely efficient and reliable fixed inductor. It is capable of withstanding extremely high temperatures and corrosive environments, due to its heat-resistant ceramic body and metal cover. Furthermore, its efficient flip chip mounting feature helps reduce its temperature rise and size. Therefore, this device is widely used in d.c – d.c converters, power supplies, and other electronic devices that require a high level of inductance.
