S0402-33NJ2

Fixed Inductors are electronic components used to store energy in an electric field and then modify and control current flow in electric circuits. The SO402-33NJ2 is one of the most commonly used fixed inductors due to its wide-range applications as well as relatively low cost. This article will provide an overview of the SO402-33NJ2 application and working principle.

Applications

The SO402-33NJ2 is applied in various industries, especially in the power electronic components industry for its extensive operating conditions. Its high current capability, high temperature resistance and low DCR (differential current resistance) make the SO402-33NJ2 quite popular in the following fields:

• Motor control systems for its excellent starting performance.
• Voltage converters for its low ESR (equivalent series resistance).
• Switch-mode power supplies for its high temp resistance, capable of continuous operation at 100°C.
• Inverters and resonant circuits for its high-performance load and frequency.
• Power dividers and other high-frequency circuits for its oversized core to offer better noise reduction and insertion loss.

The SO402-33NJ2 may also be utilized in other areas, such as EMI filter input / output, voltage doubler, uninterruptable power supply (UPS) system as well as a wide variety of other power-related circuits.

Working Principle

The SO402-33NJ2 is built using a simple coil wrapped around a non-magnetic core. When there is an electric current flow, a magnetic field is generated and stored. This stored energy can then be used to control or modify the current flow. This concept is basic to most of the inductor operations.

The SO402-33NJ2 performs the operation by using a core made up of ferrite material. This particular component has a wide frequency range of 0 to 120MHz, and is suitable to resist temperatures from -40 to +100°C. Apart from its wide range of applications, this device can also have an excellent impact on signal noise reduction, as the core size is slightly larger than traditional inductors.

To ensure reliability and excellent performance, a series of tests and measurements are performed regularly. We can measure the temperature, frequency and DCR to evaluate the performance and provide value to customers.

Conclusion

The SO402-33NJ2 fixed inductor is an extremely popular electronic component due to its wide range of applications, from motor control to EMI filter. Its excellent performance under extreme temperature and high frequency has made it an ideal choice for many power-related applications. With a careful selection and proper tests, customers can rest assured that they can get the most out of this popular component.
