Fixed Inductors

An inductor, often called a coil, choke, or reactor, is an electrical component used to manage electrical current flow across electrical circuits. It is an electrical coil consist of one or more turns of wire. In fixed inductors, also known as iron core inductors, it consists of a conductive coil with a ferromagnetic core, which can increase current flow through the inductors. One such inductor is the 1944R-11F.

1944R-11F

The 1944R-11F is a fixed inductor from the Radial Lead Inductors series of rubber-covered, radial lead inductors for general purpose applications. It is available in 10 values (10UH-100UH) across 8 current ratings (2A-8A) and various package sizes (3mm, 4mm, 5mm,6mm). The typical inductance tolerance is ±20%, an operation frequency up to 1MHz (depends on the current) and a maximum operating temperature up to 125°C.

Application Field

The 1944R-11F is suitable for applications such as power supplies, speaker circuits, flyback transformer, buck converter, and low pass filter. It is also used in electronic ballasts, switch mode power supplies, and automotive electronics, among many other uses.

Working Principle

The working principle of the 1944R-11F is the same as for any other fixed inductors. It works on the principle of Faraday’s Law. When current is passed through the coil, a magnetic field is generated, and this magnetic field, in turn, creates an opposing force to the passing current, limiting the current. This creates a constant inductance in a fixed inductor, like the 1944R-11F, which doesn’t change, regardless of the amount of current flow.

The 1944R-11F has several key features that make it ideal for a wide range of applications. It has high energy storage capabilities, low heat generation, high self-resonant frequency, and low profile construction. It also has good noise immunity, high attenuation for EMI (electromagnetic interference), and good radial radiated emissions characteristics.

The 1944R-11F is a reliable, low-cost solution for most general purpose applications. It is a great choice for low-current application, high-frequency filters, and other applications that require consistent inductance across a wide range of operating frequencies.

Overall, the 1944R-11F is a great choice for applications that require an inductor with good reliability, efficiency, and consistent performance. It has a wide range of values, current ratings and package sizes, and excellent performance characteristics, making it a great option for most general purpose applications.
