Fixed Inductors

A fixed inductor is an electronic device that has a certain inductance value, which is determined by its shape and size. It is made of a core material, usually a ferrite, and is wrapped with a coil of wire with both ends of the coil connected to a forming the inductor. Fixed inductors are used in many electronic circuits.

ER1641-221JR application field and working principle

The ER1641-221JR is a fixed inductor designed for use in electronic systems, such as amplifiers, consumer-electronic devices and regulated power supplies. This fixed inductor has an inductance value of 221uH and is rated for operating temperatures between –25 and 125 degrees Celsius. It is also RoHS compliant and comes with a one-year warranty.

The ER1641-221JR fixed inductor is made from a ferrite core material that is wrapped with a cylindrical steel coil. The coil is wound clockwise, and the two ends of the wire are connected to a terminal, forming the inductor. The current flowing through this inductor produces a magnetic field that can be used to store or transfer energy. This fixed inductor is usually used in passives electronic circuits to filter and block higher frequencies, while allowing lower frequencies to pass through.

The ER1641-221JR fixed inductor is used in many types of circuit designs for various applications. It is often used as ferrite beads on EMI suppressors, which is used for protection against interference in electronic systems. Other applications where this fixed inductor may be used include as a transformer for impedance matching to increase power efficiency, LC filters for removing unwanted frequencies, and as coils in antennas for wireless communications.

In short, the ER1641-221JR fixed inductor is a reliable and durable component for many electrical circuits. Its inductance value is helpful in providing the required energy storage and transfer, and it is rated for operating temperatures between –25 and 125 degrees Celsius. It is also RoHS compliant and comes with a one-year warranty.
