ER1641-301JS

The ER1641-301JS is a fixed inductor, a type of electrical component that uses coil wound around a core to store energy, most often used to filter signals and provide the necessary inductance to electrical circuits. In this article, we will be exploring the application field and working principle of this particular part.

The ER1641-301JS is designed to provide suitable performance when coupled with a capacitor in a low-pass filter circuit, as well as circuits which are related to noise control or electromagnetic interference. It is effective in high-frequency, high-current circuits, as well as circuits where electromagnetic compatibility (EMC) is required. In other words, it provides excellent attenuation characteristics for noise frequencies in the circuit.

The ER1641-301JS features an inductance value of 1.2 μH, a tolerance of 5%, an operating temperature range of -55°C to 125°C, a DC current of 1.3A, and a saturation current of 6.9A. The body of the inductor is 2.2X1.9X1.0mm, with a diameter of 0.45mm. All of these specifications are designed to provide the user with optimized performance across a wide range of applications.

The operating principle of an inductor involves the creation of a magnetic field around a coil of wire, when a current is passed through it. The more current that passes through the coil, the stronger the magnetic field becomes, and the more energy it can store. The stored energy is then released when the current is switched off, as a change of current would cause the magnetic field to collapse, inducing a current in the coil.

The ER1641-301JS is designed for efficient energy storage and release to effectively filter signals and reduce noise in high-frequency circuits. It features a discrete core and ultra-flat winding construction to ensure improved EMC compatibility, while its special winding construction also helps optimize the noise suppression characteristics and current-handling capabilities.

Other features of the ER1641-301JS include a minimum insulation distance of 0.3mm to ensure good mechanical and electrical properties, an excellent self-resonant frequency of 7GHz, and an optimized bond wire structure for better reliability. All of these factors combine to make this inductor one of the most reliable and efficient for EMC applications.

In conclusion, the ER1641-301JS is a fixed inductor designed to provide optimal performance when used in applications related to noise control and electromagnetic compatibility. It features a unique winding construction for improved noise suppression properties, while its discrete core construction ensures excellent performance at high frequencies. This makes it an ideal solution for a variety of applications, from low-pass filter circuits to high-current, high-frequency ones.
