Fixed Inductors

Fixed inductors are passive electrical components that store energy in a magnetic field when energized by an electric current. They are designed to withstand a certain amount of current and are often used in applications such as limiting current, filtering, storage, and power conversion. Examples of fixed inductors include buck, boost, and flyback inductors as well as high-frequency transformers.

LQH3NPN220MMRE application field and working principle

The LQH3NPN220MMRE is a small, high- frequency surface-mount fixed inductor. This inductor is especially suitable for mobile devices due to its tiny size. It features an inductance of 220mH, a maximum DC current of 3.4 A, a Q-factor of 250, and an operating temperature range of -40°C to +85°C. In addition, its rated voltage is 6.5 V and its rated ADC is 43.5A.

Due to its small size, the LQH3NPN220MMRE is ideal for use in portable or compact electronics, such as mobile phones, PDAs, GPS receivers, MP3 players, and digital cameras. It can also be used in many high-frequency applications such as high-end RF modules, RF amplifiers, and other RF circuits. This tiny inductor is constructed using a special core material capable of producing high-frequency and high-quality inductance.

The LQH3NPN220MMRE is designed to maintain its inductance over a broad temperature range, making it suitable for high-efficiency application. It can provide stable, uniform, and low-resistance performance in a wide range of applications. The inductor features a strong laminate core material with excellent saturation characteristics and low temperature-dependence.

The working principle of the LQH3NPN220MMRE is based on Faraday\'s Law of Induction, which states that an electric current produces a magnetic field which can induce a voltage in a conductor. As an electric current flows through the inductor, it produces a magnetic field which induces a voltage in the windings. This induced voltage opposes the applied voltage, thus providing a form of electrical resistance that is proportional to the amount of current flowing through the inductor.

The LQH3NPN220MMRE utilizes a combination of magnetic field intensity and saturation characteristics to provide the desired performance. As the current increases, the magnetic field intensity increases, resulting in an increase in the inductance. This gives the inductor the ability to maintain a relatively stable inductance over a wide range of currents. In addition, the saturation characteristics of the core material result in greater energy storage capabilities while also protecting the inductor from overheating.

The LQH3NPN220MMRE is an excellent choice for a wide range of applications that demand high-frequency and high-efficiency inductors. In addition, its small size makes it an ideal choice for portable electronics. This versatile fixed inductor can provide excellent performance in a variety of high-frequency applications.
