Introduction

S0402-27NF3S is a fixed inductor from Vishay Intertechnology. This type of inductor is widely used in both commercial and residential applications. It is designed to have an extremely high quality, offering both high-caliber performance and reliability. The S0402-27NF3S is an excellent choice for applications that require a low cost, high-performance inductor.

Overview of Fixed Inductors

Fixed inductors are inductors that are designed for efficiencies and feature a fixed inductance. The type of fixed inductor used in the S0402-27NF3S is a ferrite core inductor, providing a cost-effective solution. This type of inductor operates by generating a magnetic field when current is applied. This magnetic field creates an opposition to the current, resulting in reduced voltage and increased current when the voltage is too high.The S0402-27NF3S is a 1.2μH fixed inductor with a rated current of 500mA (maximum) and an operating temperature range of -40°C to 85°C. It has a highly reliable structure that is resistant to mechanical stress, vibration, and environmental exposure. The inductor is rated to be AEC-Q200 compliant, ensuring that all safety and reliability requirements have been met. The S0402-27NF3S is ideally suited for use in electronic circuits, such as boost converters, dc-dc converters, RF amplifiers, and LC resonant circuits. It is also suitable for low power motor control and other automotive applications. The inductor is rated to have a tolerance of ±20% and a temperature coefficient of -25°C to +30°C.

Working Principle of the S0402-27NF3S

The working principle of the S0402-27NF3S is based on the principle of Faraday’s law of induction. This law states that when a varying magnetic field is present, an electric current will be induced in a closed circuit. The rapidly changing magnetic field of the inductor will induce electric current in the circuit, and this current is used to increase or decrease voltage or power over a given period of time.When current is applied to the S0402-27NF3S, a magnetic field is created within the core. This magnetic field induces a voltage in the windings of the inductor, which is proportional to the rate of change of the magnetic field. This induced voltage opposes the applied current, resulting in reduced voltage and increased current when the current is too high. This is how the S0402-27NF3S is able to regulate the power or voltage in a given circuit.

Conclusion

In conclusion, the S0402-27NF3S is a high-quality fixed inductor from Vishay Intertechnology. It is designed to be highly reliable and compliant with AEC-Q200 safety standards. It is suitable for use in a wide range of applications, including low power motor control, RF amplifiers, boost converters, and more. The working principle of the S0402-27NF3S is based on Faraday’s law of induction, and it operates by generating a magnetic field when current is applied. This magnetic field induces a voltage in the windings of the inductor that opposes the applied current, resulting in reduced voltage and increased current when the current is too high.
