HSMTER122 Chip Common Mode Inductor

HSMTER122 Chip Common Mode Inductor in the HSMTER122 Chip Common Mode Inductor circuit is a hollow coil, or coil with a magnetic core, which can only pass through small current and withstand low voltage. And the power inductor also has hollow coil, also has the magnetic core, the main characteristic is wound with thick wire, can withstand tens of amps, hundreds, thousands, even tens of thousands of amps. The power patch inductor is divided into two types with and without a magnetic mask, mainly composed of magnetic core and copper wire. In the circuit mainly play the role of filtering and oscillation Our products meet EU standards and are exported to China and other countries all over the world.
Product Description

​1.  Product Introduction of HSMTER122 Chip Common Mode Inductor


HSMTER122 Chip Common Mode Inductor: The full name Surface Mounted Devices is essentially a two-way filter: on the one hand, to filter out common-mode electromagnetic interference on the signal line, on the other hand, to suppress itself from emitting electromagnetic interference, so as to avoid affecting the normal operation of other electronic devices in the same electromagnetic environment.


Our high-quality SMD common mode inductance solves low-mode noise signal suppression interference sources for customers, improves productivity and quality reliability in installation, and is favored by Chinese and European customers.
