Fixed inductors are electrical components that have the capability to maintain a fixed inductance when power is applied. The inductance is dependent upon the number of turns in the wire coil and the perimeter of the coil. Inductors have the capability to store energy or block alternating current signals due to their inductance property. They are commonly used in radio frequency (RF) circuits and are found in various applications such as RF antenna, power supplies, and filter circuits.

The LK2125R68M-T is a fixed inductor from Laird Technologies. It is a SMD unshielded power inductor designed to fit in a 1220(3020 metric) package size. Its inductance value is 2.12mH and it has a DCR of 0.56Ω at 25°C. It is rated for an operating temperature range up to 220ºC with an ambient temperature up to 70°C. It is made with a ferrite core and is capable of handling DC current up to 4A.

The LK2125R68M-T can be used in a variety of applications, ranging from automotive electronics to consumer electronics. It is capable of providing both high and low frequency power to a variety of components. The main application includes power line applications, such as pre-regulators, battery chargers, DC-DC converters, power filtering, etc. It can also be used in filter blocks for by-pass and sectional switching of multiple matrices, as well as for high frequency switching circuits.

The working principle of the LK2125R68M-T involves the use of Faraday’s law of induction. When a current is applied, an electromagnetic field is created around the inductor coil, which in turn induces a voltage across the ends of the coil. This voltage is in direct proportion to the rate of change of the current. As the current increases or decreases, the voltage across the coil either increases or decreases accordingly. The inductance is determined by the number of turns and the area of the coil. The inductance can also be adjusted by changing the turns in the coil, the core material, the geometry of the coil, and the amount of winding on the coil.

The LK2125R68M-T is a fixed inductor with excellent high and low frequency performance. It is an ideal choice for use in a variety of circuits and applications, due to its small size and high resistance to temperature fluctuations. Its main advantages include excellent high frequency characteristics, high efficiency, and low noise levels.
