Ferrite beads and chips, such as EXC-ML20A390U, are widely used components for filtering in many electronic applications. The ferrite bead is a non-polarized passive electrical component typically used in electronic circuits as a voltage or current limiter. Its name is derived from its core, which contains iron oxide or ferrite. The EXC-ML20A390U ferrite beads can be found in wide range of applications including power electronics, industrial controls, instrumentation, computing, consumer electronics, communication systems, and wireless.Ferrite beads are generally used for applications requiring high inductance and high frequency current suppression. This is accomplished through the ferrite bead’s core, usually composed of iron oxide or ferrite material, which acts as a resistor to high frequency signals. Ferrite beads have a greater resistance to these signals, compared to the copper wire or other passive incorporated into the circuit. In addition, since ferrite material is also highly susceptible to magnetism, ferrite beads also function as a magnetic shield, providing effective filtering from both induction and radiation.The EXC-ML20A390U ferrite bead has a nominal impedance of 39 ohms and a rated current of 20 amperes at 1 MHz. It has a wide operating temperature range of -55 to +105° C, making it suitable for a wide range of applications. The package of the EXC-ML20A390U ferrite bead has an insulation voltage rating of 100V AC/DC and is constructed from ceramics. It is also RoHS compliant, which means it is free of hazardous materials, a must for electronic components.The EXC-ML20A390U ferrite bead has a number of advantages that make it ideal for applications requiring efficient snubbing of pulses and high frequency signals. The resistance of the ferrite material allows for a high level of filtering while the low temperature coefficient helps to keep signals from unexpected spikes and drops in temperature. In addition, the bead has excellent thermal and DC characteristics, making it suitable for all kinds of power control circuits and voltage regulator designs.The working principle of a ferrite bead is based on the principle of induction. A ferrite bead has a ferrite core and two coil windings, wound in the opposite direction. When a current passes through the coils, the ferrite core amplifies or increases the impedance of the coil. This increased impedance attenuates high frequency noise, resulting in reduced EMI. Additionally, due to the magnetic properties of the ferrite core, the bead also provides effective filtering from both induction and radiation.The EXC-ML20A390U ferrite bead can be used in a wide range of applications for protection, filtering, and snubbing of high frequency noise in power systems. It is typically paired with power lines, motor lines, and other power sources to improve voltage regulating performance. It can also be used in digital circuits to reduce the effects of EMI. The bead is ideal for professional power system applications, where high frequency noise suppression is a must.Ferrite beads and chips, such as the EXC-ML20A390U, offer a wide range of benefits for filtering and noise reduction. Its wide range of operating temperature, high inductance, and excellent DC and thermal characteristics, make it suitable for a variety of applications, including power electronics, industrial controls, instrumentation, computing, consumer electronics, communication systems, and wireless. The ferrite bead is an essential component for EMI suppression and is a great choice for use in a variety of applications.The specific data is subject to PDF, and the above content is for reference
