Fixed inductors are passive components, used to create an electrical field in a circuit to create a constant current or voltage, and in some cases an audio signal. Fixed inductors are divided into two major categories – power inductors and RF inductors, based on the type of fields they are designed to create. The S0402-27NF3B fixed inductors are from the RF inductor category and used mainly in radio frequency circuits.

Design and Construction

The S0402-27NF3B inductor is a very small size RF component, measuring 2×0.60mm. It is a high-performance device with an internal construction of ferrite core, wound coil, and a subminiature RF shield. The device comes with a lacquered copper coil, a metal alloy shell, lead wires, and a lead frame. The lead frame ensures the proper components attachment on to the main body of the device.

Application Fields

The S0402-27NF3B fixed inductor is designed for use in high frequency electronics such as in radio frequency (RF) circuit, broadcast radio, and television receivers, FM modulators, transmitters, amplifiers, video frequency synthesizers, transmitting, sensing/detecting, etc. Also, it is used in RFID, medical, wireless communication, wireless power transfer, and music audio equipment.

Working Principle

The inductor works by creating a constant electromagnetic field in order to increase the voltage in a circuit. When current is passed through the inductor, a magnetic field is created around it with the strength of the field depending on the inductance of the inductor. When current is cut off from the inductor, the magnetic field collapses generating a voltage spike which can be used for a number of applications such as for filtering, token ring, and radio frequency amplifiers.

The S0402-27NF3B fixed inductor is designed with a high degree of precision. The small size and the high-performance make it a suitable device for a wide range of high-frequency electronic applications. Given its size and shape, the inductor can be used in areas with tight space constraints.
