Fixed inductors are passive electronic components that offer an inductance value and are used in combination with capacitors in electronic circuits. They are also known as fixed inductance coils, as they consist of helically wound wires of copper or aluminum that are kept together inside a body of non-magnetic material. The 1812R-390J is a fixed inductor characterized by the following features:

Dimensions: The 1812R-390J has a dimension of 18.1mm x 12mm with a height of height of 5.6mm.

Inductance Range: This fixed inductor provides an inductance range of 0.3uH - 39uH.

Inductance Tolerance: This device has a tolerance of ±10%.

Temperature Range: The temperature range of this device is typically -55°C to +125°C.

The 1812R-390J is designed for use in a variety of applications. It is commonly used in power line filters, power factor controllers, AC/DC converters, motor controllers, and other power electronic circuits. It also has a wide range of applications in telecommunications, automotive electronics, and utility control systems.

The working principle of the 1812R-390J is based on Faraday’s law of induction. The inductance of this fixed inductor is created when a varying current passes through a coil. As current passes through the coil, a magnetic field is created, inducing an electromotive force in the coil. This induced current produces an opposing current to the original current, resulting in an increased voltage across the inductance. The more turns the coil has, the higher the inductance produced.

The 1812R-390J is designed to be tolerant of high temperatures and harsh environmental conditions. It is constructed with a flame-retardant polyester-imide (FR-PI) coating, which protects it from moisture, dust, and other contaminants. It is also resistant to dielectric breakdown caused by high temperatures and radiation. In addition, it has an unmatched temperature coefficient of -400ppm/°C.

The 1812R-390J is a reliable and durable fixed inductor that is well suited for a variety of applications. It offers high stability and performance, with a low temperature coefficient and high insulation resistance. It also offers a wide operating temperature range, making it an ideal choice for power applications in a variety of industries.
