SMT common mode line filter
Advantages:
Constructed from ultra-thin mixtures of iron, nickel and zinc oxides, Ming Da‘s ferrite common mode chokes are characterized by their size, light weight, low cost, and high reliability. They provide superb EMI reduction while remaining open to normal circuit operation. Other benefits include:
A common mode filter for distortion-free noise removal from transmitted signals. Optimized for transmission of high quality signals.
- Best filter for countering the common mode noise resulting from data signal processing by PCs, phone equipment, etc.
