Fixed inductors are electronic components in an electronic device circuit whose inductance is fixed. The 1782R-31H is a particular type of fixed inductor, designed specifically for use in high-frequency switching power supplies. It is composed of a core material, wire, and bobbin material.
The core material is key to the use of the 1782R-31H because it establishes the basic inductance range of the component. The most common core material used is iron-powdered (FeSi) silicon steel. This has the advantage of allowing for low-level magnetic flux resulting in low losses. Alternatively, ferrite can also be used.
The wire used is typically enamelled copper wire, known as ECW. This is because it offers good stability and is suitable for high-frequency operation. Different wire sizes are used depending on the size of the component. Typically, the thicker the wire, the lower the resistance and the higher the inductance range.
The bobbin material is also important as it is designed to protect the components from mechanical and environmental stresses. The 1782R-31H typically uses a nylon bobbin material. This has the advantage of providing good electrical and thermal insulation.
The 1782R-31H has a wide range of application fields including high-frequency switching power supplies, power semiconductor converters, and other low power electronic circuitry. It can be used to build high-frequency filter circuits, bypass capacitors, as well as DC to DC converters.The 1782R-31H operates according to the principle of electromagnetic induction. Electromagnetic induction is a phenomenon in which a current can be induced in a conducting material when a magnetic field interacts with it. This current is used as a source by the 1782R-31H, and the inductance that results is in proportion to the number of turns in the wire and the permeability of the core material.
The 1782R-31H is a highly reliable and efficient fixed inductor, suitable for a wide range of applications. Its robust construction and low mass make it ideal for use in high-frequency switching power supplies, power semiconductor converters, and other low power electronic circuits.
