Fixed Inductors

A fixed inductor, also called a choke, is an electrical component that stores energy in the form of a magnetic field when current passes through it. Using this property, they are used to filter out high and low frequencies in an electrical circuit. In particular, the SC3340F-6R8 is a type of fixed inductor.

Application Field of SC3340F-6R8

The SC3340F-6R8 is a small, surface mount, fixed inductor ideal for applications in switching power supplies, DC-DC converters, cell phone audio lines, and other portable electronic devices. It features low ESR, low cost, and low noise operation. Additionally, as a surface mount, the design footprint of this component is much smaller than traditional through-hole components, making it ideal for space-constrained designs.

Working Principle of SC3340F-6R8

The SC3340F-6R8 works through the principles of inductance, resistance, and capacitance. Through magnetic flux, the inductor resists any changes in an input current, regulating voltage by limiting the amount of current flow. The resistance of the inductor is proportional to frequency and is inversely proportional to the physical size of the components.

Meanwhile, capacitance occurs when two wide metal plates are placed parallel to each other and separated by insulating material. It stores electric energy in the form of charged particles, and is an important factor in the performance of inductors. The capacitance of the SC3340F-6R8 is 0.01μF.

These principles hold true for any type of inductor, though depending on the specific model, inductance, capacitance, and resistance values will vary. The SC3340F-6R8 provides an inductance of 6.8μH ±30%.
