The ER1641-824JR is a fixed inductor developed by Panasonic that finds utility in a variety of applications. It is classified as a fixed inductor. Fixed inductors are devices that contain a coil of wire which provides inductance, or resistance to changes in electrical current according to Faraday’s law of induction. This resistance results in the generation of a magnetic and an electric field in proportion to the amount of current flowing through the coil. Generally, the ER1641-824JR is used in power supplies, signal line filtering, and battery charging.

The ER1641-824JR has a wide range of operating temperatures that span from –40°C to +105°C. It is equipped with a tapping point at the beginning, middle, and end of its inductance range. This tapping point makes it easier to select the correct inductance values and is particularly useful when tight tolerance is needed. The ER1641-824JR also has a wide tolerance of ±25% and can handle currents from 10.6 to 75 mA.

The working principle of the ER1641-824JR is grounded in Faraday’s law of induction. This law states that when a wire is placed in a magnetic field, an electromotive force is induced in it, causing a current to flow. This current is further increased by the presence of a resistive element in the magnetic coil, resulting in an increase in inductance. The inductance generated by the ER1641-824JR is directly proportional to the number of turns in the coil and the applied current.

In addition to its ability to provide electrical isolation, the ER1641-824JR is also equipped with various protection features. It has an integrated temperature sensor that protects it from crack and ensures that the temperature of the coil does not exceed a certain threshold. It also contains an insulation layer that prevents any high voltage surges from entering the coil. The sensor and insulation layer help to increase the lifespan of the ER1641-824JR by protecting it from external electric shocks.

The ER1641-824JR is an ideal device for use in a variety of applications including power supplies, signal line filtering, and battery charging. It can operate within a wide range of temperatures and can withstand high current and voltage levels. Finally, its integrated temperature sensor and insulation layer help to protect it from electric shocks and ensure its longevity.
