1. Product Introduction of SMTST4 Chip Common Mode Inductor
SMTST4 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.
