Fixed Inductors: ER1641-221KS

The ER1641-221KS is a small, axial leaded, fixed, ferrite core inductor. It can provide efficient energy storage using its high saturation current. It offers an ideal solution for applications where size and cost are important considerations. This component is characterized by low DC and AC resistances, as well as high quality factor (Q-factor) over the entire working frequency range.

Applications

The ER1641-221KS is suitable for a variety of applications, including television receivers, audio amplifiers, water-proof sealed loudspeakers, power supplies, audio signal processing equipment, and home entertainment systems. It is also suitable for high current and signal filtering applications, such as cameras and other sensitive equipment. It also finds use in car audio applications, as well as LED lighting systems.

Working Principle

The ER1641-221KS works by creating a magnetic field in the form of an inductance. This is done by passing electrical current through a coil of tightly wound wire called a winding. The winding means that the electrons flowing through the wire have to take a longer path to cross this part of the circuit. This causes a magnetic field to be generated, which will cause an opposing force to be applied to the current. This is known as inductance. The inductance will generate an energy storage element that will provide more power than is used in the winding.

The ER1641-221KS utilizes a phenomenon known as hysteresis to further enhance its power storage capabilities. Hysteresis is a measure of how quickly the magnetic field within the inductor changes upon the flow of current. The higher the hysteresis, the more energy that can be stored in the inductor. This allows the ER1641-221KS to cope with spikes in current for short periods of time. Thus, the inductor will provide improved energy storage at higher frequencies.

The ER1641-221KS is also designed to be shock and vibration proof. It is designed to withstand harsh environments, making it ideal for a variety of applications. It also has a high temperature rating, so it can be used in high temperature environments.

In summary, the ER1641-221KS is a small, axial leaded, fixed, ferrite core inductor. It offers an efficient energy storage solution for applications where size and cost are important considerations. It works by creating a magnetic field in the form of an inductance, and further utilizes hysteresis to enhance its power storage capabilities. It is designed to withstand shock and vibration, as well as high temperature environments.
