common mode choke manufacturers
Advantages:
1.Constructed from polycarbonate case, polyurethane potting, current-conpensated ring core double choke with ferrite core.
2.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.
3.Best filter for countering the common mode noise resulting from data signal processing by PCs, phone equipment, etc.
4.Through-hole type Common Mode Line Filter
5.Ring core with the core materials of NiZn and MnZn
6.Recommended solder profile: Reflow
7.High current up to 2500 mA
8.Package: tape&reel packaging
9.Quick lead time and low MOQ
10. Full inspection before delivery
11.High-precision winding construction with spacer improves isolation in offending circuits and ensures consistent reliability
12.Various operating temperatures and current match capabilities over a broad range of inductance values
