S0402-6N8F3C

Inductors are electrical components that store energy in the form of a magnetic field when electric current passes through them. Fixed inductors are components that have a fixed inductance value, meaning that their inductance will not change with changes in the supply current or frequency. The S0402-6N8F3C is a surface-mount fixed inductor from one of the leading providers of inductors in the world today.

The S0402-6N8F3C is a miniature, multi-layer, surface-mount, fixed inductor with a mounting profile of 0.4” x 0.2”. It has a maximum inductance value of 6.8uH, a maximum DC resistance of 0.06Ω, and a maximum current rating of 1.59A. The inductor is built using an iron-powder core and is rated for an operating frequency range of 0.2MHz to 1GHz. The recommended operating temperature range for the device is -40°C to +85°C. The S0402-6N8F3C is rated for a maximum capacitance of 10nF. The inductor is RoHS compliant and is UL/CUL listed.

The S0402-6N8F3C and other fixed inductors are used in a wide range of applications from consumer electronics to medical equipment. The device is used in power supplies, radio frequency (RF) circuits, DC-DC converters, and low-noise analog circuits. In consumer electronics, the fixed inductor is used in the power section of laptops, tablets, and smartphones. In medical equipment, it is used in hearing aids, ECG machines, and other imaging equipment. The inductor is also used in home appliances such as microwaves, TV sets, washing machines, and refrigerators.

The working principle of a fixed inductor is based on Faraday\'s law of induction. When a varying magnetic field passes through a coil, an electric current is induced in the coil. The magnitude of current depends on the rate of change of magnetic flux, the inductance of the coil, and the type of the coil. When the current flowing through the inductor changes, a voltage is generated across the inductor due to the inductance. This voltage opposes the change in current as described by Lenz\'s law. In other words, a voltage drop is created in the inductor when the current flowing through it changes, resulting in a decrease in the current to reduce the voltage drop. This drop in current is known as inductive reactance. As the frequency of the alternating current increases, the inductive reactance, and hence the voltage drop across the inductor, also increases.

In summary, the S0402-6N8F3C is a miniature, multi-layer, surface-mount, fixed inductor with a maximum inductance value of 6.8µH. This device is widely used in consumer electronics and medical equipment, and has a wide operating frequency range of 0.2MHz to 1GHz. Its working principle is based on Faraday\'s law of induction and Lenz\'s law, with the voltage drop across the inductor caused by the inductive reactance increasing with increase in the frequency of the alternating current.
