Fixed inductors are passive electrical components designed to store energy in the form of magnetic fields when a current is passed through them. The ER1641-105KP is one such inductor. This component has a 0.05 Ohm rating, is rated for currents up to 2A, and its inductance is 10uH. Its operating temperature range is -40 to 85ºC and has a pulse ratio of 3.2.

The ER1641-105KP is used in a wide range of applications such as DC-DC converters, buck and boost converters, as well as switching mode power supplies. It can also be used in radio frequency (RF) transmission lines and low-cost switching filter circuits.

The working principle of a fixed inductor is based on Faraday’s law of induction, which states that an electric current will induce a magnetic field, and a changing magnetic field will induce an electric current. When a current flows through an inductor, the current generates a magnetic field around the inductor, which in turn induces a voltage opposing the current that produced it. This opposing voltage is known as the back emf.

The ER1641-105KP has a bobbin-wound design and is composed of a ferrite core and two lead wires. The ferrite core forms the inductive element of the device by storing magnetic energy which is created when current passes through it. The lead wires attach the inductor to external circuit components.

The amount of inductance of an inductor is dependent on the number of turns, the radius of the coil, and the permeability of the core material. In the case of the ER1641-105KP, the number of turns is 1, the radius of the coil is 0.4mm, and the permeability of the core material is 47,000. This combination of factors results in a constant 10uH inductance rating.

The ER1641-105KP is an ideal choice for many types of low-cost, small signal-current circuits. It is a robust and reliable component which can withstand a wide range of temperatures and current ratings. Its high frequency characteristics make it suitable for use in radio-frequency circuits, and its compact design allows it to be used in tight space applications.
