Fixed inductors are electronic components used in electric circuits to oppose constant current and reactance. They are made of a coil of wire wrapped around a core, usually of iron and can be made in two categories: air cores or ferrite cores. Fixed inductors are used in numerous applications such as in the automotive, consumer electronics, medical, industrial automation, telecommunications and aerospace industries. Among the various types of fixed inductors, ER1641-824JM stands out as one of the most popular options available today.

The ER1641-824JM fixed inductor is a 4-pin shielded device that consists of a ferrite core with a wire coil and is especially designed for use in switch-mode power supplies (SMPS) and in other high-frequency applications. It features an inductance value of 8.2uH, a peak current rating of 1.9A, a saturation current of 2.4A and an SRF of 480MHz. The ER1641-824JM also has a temperature coefficient of -10%/deg C and its operating temperature range is between -40°C and +125°C, making it ideal for a wide range of applications.

The working principle of ER1641-824JM is relatively simple. It works on the Faraday’s law of induction which states that when a conductor is placed in a changing magnetic field, an electric current is induced in the conductor. When an electric current is passed through the conductor (coil) in the inductor, a magnetic field is created in the core and this magnetic field induces a back electromotive force (back EMF) in the conductor. This back EMF opposes the main EMF and opposes any changes in current, thereby limiting the current to a pre-determined level.

ER1641-824JM fixed inductors are widely used in power supplies, especially in SMPS. It provides protection for the power supplies against higher current levels and protects the components inside the power supplies from damage due to overcurrent. It is also used in regulating and controlling current in automotive components, filtered AC and DC circuits, and in various applications where a stable current is required.

ER1641-824JM fixed inductors are also used in various telecom and networking applications. The inductor provides power filtering which reduces radio frequency interference and helps to stabilize the current to the desired levels. It is also used in various consumer electronics such as audio systems, video devices and other electronic applications where it plays an important role in providing a constant voltage.

ER1641-824JM is becoming increasingly popular in all sorts of applications due to its wide operational range, high saturation current levels and SRF rating, and temperature coefficient. It is a reliable and efficient component for any device or system that requires constant current levels or protection from overcurrent. By necessity, it is an essential part of modern day electronic devices and machines.
