Fixed inductors, also known as chokes, are electrical components that produce a magnetic field when energized. The energy is then stored within the inductor’s coils, which can be used to reduce the amount of noise produced by power supplies and other circuits. The 744912139 inductor is a type of fixed inductor designed to support a wide range of applications. This article provides an overview of the 744912139 inductor’s characteristics, applications, and working principles.
Characteristics
The 744912139 fixed inductor is a small, surface-mount component made from high-quality materials, including copper, tantalum oxide, and ferrite. These components have a maximum operating voltage of 8.4 V and a maximum current rating of 5.7 A. The inductance range of the 744912139 can vary from 0.01 to 2mH, and the impedance can range from 10 to 100 ohms. The 744912139 is also small for its power capacity, measuring only 4.3mm in width and 4.3 in length.
Applications
The 744912139 inductor is suitable for a wide range of applications, including power supply switching circuits, LED lighting systems, and DC-DC converters. This component is also used in consumer electronics such as mobile phones, tablets, and computers. Additionally, it is sometimes used in audio amplifiers, radio receivers, and other audio electronics.
Working Principle
The working principle of a fixed inductor is based on the fact that when current passes through a coil, a magnetic field is generated. The magnetic field then induces a voltage in the coil, causing the current to decrease over time. This decrease in current is known as inductance and is typically measured in units of henries. The 744912139 inductor utilizes this principle to reduce noise in circuits and power supplies.
The 744912139 inductor is a powerful component that can be used in a variety of applications. It is capable of producing high inductance and impedance levels, while also providing a relatively low operating voltage and current rating. Furthermore, it is small for its power capacity and can be easily integrated into most circuits and systems.
