Fixed inductors refer to inductors in which the inductance is a fixed component in the circuit and does not vary much with environmental factors such as temperature and humidity.

The S0402-3N3J1 fixed inductor is a miniature inductor with a frequency range of 100MHz. It is a low-profile surface-mounted device in a 0402 form factor with a 0.9mm x 0.45mm footprint. The package body is epoxy resin with operating temperature of between -40℃ to +100℃, and ripple current rating of up to 1.4A.

S0402-3N3J1 application fields mainly include but not limited to mobile phone chargers, laptops, notebooks, white goods, industrial applications, and mobile systems. The unique features of the S0402-3N3J1 series of inductors include higher inductance in a smaller size, low DC resistance, and easily connectable terminations.

The working principle of the S0402-3N3J1 is quite simple. It consists of a coil of wire wrapped around an iron core. When current flows through the coil of wire, a magnetic field is generated which induces an electromotive force in the coil itself. This electromotive force is delayed and attenuated due to the presence of the core material, and this causes the inductance of the coil. In turn, this also causes the inductor to offer an opposition to changes in the current flowing through it, regardless of whether those changes are due to an increase or decrease in the voltage.

The S0402-3N3J1 uses this simple working principle to offer stability, reliability, efficiency and other features that make it ideal for use in a variety of applications. It is also capable of withstanding high-temperature environments and offers superior EMC performance without sacrificing impedance, making it a great choice for power supply filtering and decoupling applications.

In summary, the S0402-3N3J1 fixed inductor is a miniature inductor with a frequency range of 100MHz and a 0402 form factor with a 0.9mm x 0.45mm footprint. Offering higher inductance in a smaller size, low DC resistance, and easily connectable terminations, the S0402-3N3J1 is ideal for use in mobile phone chargers, laptops, notebooks, white goods, industrial applications, and mobile systems. Additionally, its working principle is quite simple, providing stability, reliability, efficiency and other features that make it suitable for power supply filtering and decoupling applications.
