744912182 Inductors, Coils, Chokes

Fixed Inductors are electronic components that are used to store energy, create electrical resistance, or generate a voltage across a conductor. They are made up of a magnetic core surrounded by insulated coils of wire, and are typically found in electronic applications like amplifiers, class-D amplifiers, radio-frequency (RF) amplifiers, high-power audio systems, and antenna couplers. Typically, the inductor core is made of ferrite, iron, laminated steel, or copper wire, and the coils are usually made of copper or aluminum. This makes the inductor robust and capable of handling higher voltages and frequencies.

The 7449 series of fixed inductors is designed to provide higher levels of power density than other similar components. It is made using a combination of high-temp, low-temp, and low-power inductors. The 7449 series has an optimized combination of inductance and current, maximizing energy storage and efficiency at high frequencies for improved power delivery. This component has a wide range of applications in military, aerospace, industrial, automotive, and consumer electronic products, including power supplies, power converters, and current saturation amplifiers.

The working principle of a fixed inductor is based on Faraday\'s law of induction, which states that a changing current in a conductor creates a proportional magnetic field around it. The changing current generates a changing magnetic field which, in turn, induces a voltage into the windings of the inductor. The induced voltage is proportional to the rate of change of the current, or the time derivative of the current. Thus, the voltage induced into the inductor is dependent on the frequency of the alternating current.

In a fixed inductor, the current passing through the coils creates an alternating magnetic field around them. This field then creates an electrical pulse with a period that is equal to the frequency of the changing current. The voltage induced in the inductor is proportional to the frequency of the current. This proporational relationship is known as the inductance of the inductor.

The 7449 series of fixed inductors are designed for critical applications where precision and power efficiency are essential. The inductors are characterized by a high power density, low core losses, and maximum energy storage. In addition, the 7449 series are designed to withstand high-temperature environments. With their high power-handling capability and superior heat dissipation, the 7449 series of inductors are the perfect choice for high-precision applications that require reliability and durability.
