Fixed Inductors
Fixed inductors are commonly used in a variety of electronic and electrical circuit applications. The 3094-681HS is a type of fixed inductor designed to deliver consistent, reliable performance in these circuits. This article will describe the application field of the 3094-681HS, its working principle, and other details of its construction and features.The application field of the 3094-681HS fixed inductor encompasses many uses. It can be used in DC-DC converters, switching power supplies, and other electronic equipment for controlling high currents and noise. In addition, the 3094-681HS is designed to provide inductance in low-frequency, low-impedance circuits, such as those found in appliances and other motor-operated equipment.The working principle of the 3094-681HS fixed inductor is based on Faraday’s law of induction. The device consists of a core made of a ferromagnetic material, such as an iron-cobalt alloy, wrapped with a coil of insulated copper wire. When current flows through the coil, the material in the core creates a magnetic field. This field induces an opposing current in the coil, which helps to regulate the total current in the circuit.The construction of the 3094-681HS is simple yet effective. The core consists of a ferromagnetic powder cased in an epoxy material. This powder is combined with ferrite or manganese-zinc to provide the required magnetic properties. The wire coil is formed from a single length of lightweight, high-temperature resistant copper wire, wound tightly around the core. The entire device is encased in an epoxy resin for added protection and insulation.In addition to its basic working principle and construction, the 3094-681HS has several features that help it to outperform other conventional inductors. It has an incredibly low resistance of 0.008 ohms, meaning it can carry a larger current than other inductors without heating up or becoming damaged. The temperature range of the device is also impressive, with operation possible at temperatures ranging from -55℃ to +125℃. Finally, its overall dimensions are small, measuring just 18.9 mm x 10.3 mm, making it suitable for use in confined spaces.The 3094-681HS fixed inductor is an excellent choice for applications where performance and reliability are paramount. With its Faraday-induced working principle, construction of lightweight copper wire and core of ferromagnetic material, small size, low resistance, and wide temperature range, it is the ideal choice for a range of DC-DC converters, switching power supplies, and other electronic equipment.
