Fixed Inductors are common passive device components used in a variety of electronic circuits. The SRP1040-R20M is an example of an inductor that belongs to this category. This particular inductor is designed and manufactured by Samsung Semiconductor, Inc., and is widely used in automotive applications. In this article, we will discuss the application field and working principle of the SRP1040-R20M.

The SRP1040-R20M is a ceramic-based surface-mount fixed inductor with a maximum DCR of 0.01 ohms. It has a saturation current of 10A and an inductance range of 0.047 to 0.220µH. This makes it suitable for use in a wide variety of applications, such as low-noise power supplies, switching power supplies, LED lightings, and frequency converters. The SRP1040-R20M is also highly temperature-stable and has a low ESR making it suitable for harsh automotive environments.

The SRP1040-R20M is also designed for EMI and RFI suppression. It offers excellent noise reduction capabilities, which make it suitable for use in a variety of applications including power converters and power amplifiers, automotive control systems, and motor control systems. The SRP1040-R20M can reduce EMI and RFI emissions, thus providing better protection to the surrounding environment.

The working principle of the SRP1040-R20M is based on the fact that an inductor behaves like a coil of wire when a current is passed through it. The current passing through the inductor generates a magnetic field. This magnetic field induces an electromotive force, and the inductance of an inductor is measure of how much this force will change with respect to the amount of current which passes through it. The SRP1040-R20M has a low inductance range, which makes it ideal for use in applications where EMI and RFI suppression is needed.

In conclusion, the SRP1040-R20M is a ceramic-based surface-mount fixed inductor that is ideal for use in automotive applications. It has a low DCR, high saturation current, and a wide inductance range, making it suitable for suppressing EMI and RFI in a variety of applications. The working principle of the SRP1040-R20M is based on the fact that it behaves like a coil of wire and the inductance is measured when a current is passed through it. This makes it an ideal inductor for use in automotive and other noise-sensitive applications.
