Fixed inductors, also known as chokes, are components that constrain the flow of electrical current. The S0402-4N7F2C is a specific type of inductor manufactured by AVX Corporation, and is specifically designed for use in low-current, low-power applications that require precise current control.

The S0402-4N7F2C is a tiny yet robust low-weight monolithic chip made from a ferrite core material. It has an inductance of 4.7uH with a tolerance of +/-20%, and the operating temperature range is -40 to +105 degrees Celsius. The package size is 0.04” x 0.02” (1,016mm x 0.51mm), and the weight is only 0.61mg. The maximum DC current rating is 1000mA, and the total current rating is 1.2A. In addition, the maximum AC current rating is 580mA.

S0402-4N7F2C inductors can be used in a variety of applications, including motor/switching power control, signal processing, switch-mode power supplies, charge pumps, and voltage converters. These components are also used in automotive, telecom/mobile, consumer, healthcare, and industrial electronics.

The S0402-4N7F2C is highly reliable and requires minimal power consumption. It is also RoHS compliant and lead-free according to EU directives. Furthermore, the product is immune to shock and vibration.

The S0402-4N7F2C inductor works in a similar way to a resistor, except that instead of limiting the flow of electricity, an inductor preserves that flow instead. This principle is known as inductance. Inductors operate by using one of two phenomena: self-inductance and mutual inductance.

When an electric current passes through an inductor, it generates a magnetic field, and the magnetic field then induces an electromotive force (EMF) to oppose the applied current. This process is known as self-inductance. On the other hand, when two or more inductors are placed in close proximity, they interact with one another and the field created by one oscillates the other. This phenomenon is known as mutual inductance.

The S0402-4N7F2C employs a combination of self-inductance and mutual inductance to control and constrain the flow of electrical current, making it ideal for applications that require precise current management. This device is designed to reduce both electromagnetic interference (EMI) and radio frequency interference (RFI). It is also designed to be compatible with various other components, such as processors, amplifiers, rectifiers, and voltage regulation components.

The S0402-4N7F2C is an excellent choice for low-current, low-power applications that require precise current management. Its combination of small size, high reliability, low power consumption, and compatibility with other devices make it an ideal component for a variety of applications. It is RoHS compliant, making it safe for use in the modern electronics industry. It is also resistant to shock and vibration, ensuring its long-term reliability.
