Fixed inductors are electrical components used in electronic circuits typically composed of a coil of insulated wire wrapped around a core made from a ferromagnetic material such as iron. The ER1840-36JR is a specific type of fixed inductor that was developed by Hongfar, a Chinese company known for its high-quality electrical components. The ER1840-36JR is designed for use in applications such as switching power supplies, inverters, and other consumer electronics.

The ER1840-36JR is specifically designed for high frequency and voltage applications, such as those found in switching power supplies and inverters. It features an inductance of 36 μH, a DC resistance of 0.514NΩ, a rated current of 0.32A and an Isat of 0.39A. The core of the ER1840-36JR is made from ferrite material, which gives it a high inductance to size ratio and durability. The insulation material is designed to withstand temperatures of up to 135°C.

The primary purpose of the ER1840-36JR is to reduce or “choke” power noise generated by digital signals. This noise is generated by current passing through the inductor’s coil, and is inversely proportional to the inductance of the component. That is, the higher the inductance, the lower the noise. The ER1840-36JR has a relatively high inductance value of 36 μH, allowing it to reduce power noise efficiently. In addition, its low DC resistance helps keep power losses to a minimum.

The ER1840-36JR is also commonly used in power electronics applications. In these applications, it acts as a “pre-regulator” by stabilizing the input voltage and providing a consistent output. This helps regulate the current and voltage as well as prevent the circuit from experiencing instability due to load changes. In addition, the ER1840-36JR provides immunity against fast transients, helping to improve system reliability.

In addition to its power suppression and power electronics applications, the ER1840-36JR can be used in RF (radio frequency) circuits. In this type of circuit, the inductor acts as a filter, blocking out unwanted RF signals. By filtering out interference, the ER1840-36JR helps improve overall circuit performance. The ER1840-36JR is also capable of operating at frequencies up to 5MHz, making it an ideal choice for high-frequency applications.

In conclusion, the ER1840-36JR is an ideal choice for high-frequency, high-voltage applications such as switching power supplies and inverters. Its high inductance value and low DC resistance make it an effective solution for reducing power noise and providing stable, consistent power to electronic circuits. Additionally, its Ferrite core allows it to operate efficiently at high frequencies, making it suitable for RF and other high-frequency applications. All in all, the ER1840-36JR is an excellent choice for a wide variety of applications.
