Fixed inductors are types of electronic components that can store a specific amount of energy in an electromagnetic field, and then release it when required. The 2500R-38J is one such inductor, commonly used in a range of applications.

The 2500R-38J is an axial leaded, miniature inductor, offering a high efficiency and a compact size. It has been designed for use in audio frequency circuits, power supplies and in low voltage DC lighting. Additionally, the 2500R-38J is used in modem data communications circuits, small signal switching and telecommunications equipment, and a wide range of other applications.

The 2500R-38J is comprised of a hollow polyester bobbin core, which is covered by two primary windings of enameled copper wire. The primary windings are separated from each other by a thin insulator layer. Secondary and tertiary windings are then wound over the primary windings, with all three winding layers being connected in parallel. The inductor also contains a electrical grade ferrite bead, providing high insulation resistance and a low impedance to ground. This ensures stable operation at a wide range of temperatures and frequencies, making the 2500R-38J suitable for applications with varying voltage signals.

The 2500R-38J features a flat inductance curve and can work at frequencies up to 500kHz. It’s rated to handle 1.7A @ 55°C, and over 20mOhms resistance at 13.8V. The 2500R-38J is also designed to have an insulation resistance of greater than 1000MOhms, making it an ideal solution in environments with large amounts of RF energy.

To summarise, the 2500R-38J is a highly efficient, highly reliable fixed inductor specifically designed for applications with low voltage DC lighting, audio frequency circuits, data communications circuits and more. It features a flat inductance curve, enabling it to handle up to 500kHz frequencies, and has a rated power rating of 1.7A @ 55°C, with a low impedance to ground of 20MOhms at 13.8V. It’s also designed to have an insulation resistance of greater than 1000MOhms, making it suitable for use in environments with large amounts of RF energy.
