Fixed inductors, often referred to as "choke inductors," are essentially just like their namesake suggests: a component made up of an inductor, and usually two windings, that serves to reduce AC current flow and prevent spikes and transients. They are commonly used in a wide range of applications, from analog to radio frequency, and even on-board computer and mobile device electronics. In this article, we shall be taking a look at the 103R-101KS application field and working principle, to better understand how this particular device can be utilized.

The 103R-101KS fixed inductor is an axial type, rated at 105µH. It is a self-supporting component with two solder tabs; one at each end, where the windings are wound using a single layer and double-layer technique. The winding material used is a slightly colored plastic film to provide the necessary shielding to reduce EMI. This particular inductor is also coated in an epoxy resin for enhanced environmental protection and durability.

The inductance of the 103R-101KS is determined by the number of turns of the winding and the core material used for the transformer; typically, a ferromagnetic material such as powdered iron or ferrite. It is also characterized by having an excellent AC impedance and low DC resistance. As with most inductors, the 103R-101KS has a reactive current that lags the applied voltage by an angle determined by its ‘Inductance X Reactance’.

The 103R-101KS application field covers a wide range of industries, such as automotive, telecom, network, home automation, industrial, consumer electronics, and medical. These devices are often used in power supplies, switching circuits, filters, and other applications which depend on an efficient inductor.

In terms of its working principle, the 103R-101KS is essentially a short circuit device. When subjected to an AC signal, current flows through the two windings of the inductor, generating an electromagnetic field. This field, in turn, is mainly responsible for creating the inductive reactance, resulting in reduced voltage and current levels.

At the quantity level, the 103R-101KS is sold in individual pieces, not in smaller packages. The mechanical dimensions of the device are 8.2 x 2.8 inches, with weight in the range of 5g to 6.5g. The temperature range for the device is -55°C to +125°C, with a tolerance value of +/-5%.

Overall, the 103R-101KS is an excellent fixed inductor for a variety of applications, offering excellent AC impedance and low DC resistance. Its tolerance values are quite accurate, while its mechanical dimensions and temperature range make it suitable for many circuit boards and electronic systems.
