Fixed inductors are electronic components used to store electrical energy in the form of a magnetic field. The most common types are air-core inductors, which consist of solid cores or coils made from copper or other metal conductors, and ferrite core inductors, which use ferrite materials such as iron oxide and other ferromagnetic materials to store energy in a more efficient manner. The ER1641-123JM is an air-core inductor typically used in high-frequency applications such as radio transmitters and receivers.

The ER1641-123JM is a rated 10µH, 13 Amps, radial leads, toroidal inductor, with a body diameter of 16mm and overall length of 41mm. It is manufactured using a patented winding process, which results in a compact, non-self inductor wound with a ferrite covered copper wire that maintains high efficiency and low loss over a wide range of frequencies, from DC to 790MHz. The ferrite-covered copper wire is designed to reduce skin effect losses and lower winding temperature, enabling the ER1641-123JM to provide superior Q and low DCR values over a wide frequency range.

This inductor is an ideal choice for RF applications, such as radar systems, aircraft navigation systems, satellite receivers, and high-frequency audio amplifiers. It has also found use in high-frequency switching power supply circuits, bias circuits, and active antenna circuits. Due to its high current rating and inductance, it can effectively replace multiple components in certain application designs, such as buffer circuits, VCO oscillators, and resonant circuits. The inductor’s low profile and wide operating temperature range make it an ideal choice for use in many circuit designs where size and temperature sensitivity are a factor.

The ER1641-123JM fixed inductor is based on Faraday’s law of electromagnetic induction, which states that when a changing magnetic field applied to a conductor, an electric current will be induced in the conductor. In the ER1641-123JM, the wound wire coil interacts with the external magnetic field, producing an induced current flow through the windings. This current flow creates a opposing field within the wire coil, which is produced as a result of the magnetic material properties of the core winding. In turn, this opposing field applies a voltage across the inductor, resulting in a current through the external circuit.

The ER1641-123JM fixed inductor is an ideal component for high-frequency applications, offering a wide operating temperature range, low DCR, and superior Q values. It’s small size and high current rating make it suitable for a variety of circuit designs, from amplifiers to oscillators. With its patented winding process, the ER1641-123JM ensures high efficiency and reliably operation in even the most demanding applications.
