| Large Common Mode Choke Cores And
Chokes Using Nanocrystalline Material |
 If you require much larger cores for common mode chokes
with rated currents over 100Amps these cores offer you the size to solve
these RF noise problems.
They can be used for signal lines, DC power lines, and AC power lines.
Because of the low magnetostriction these core also provide low audible
noise. Cores with base plate only, require cabling with the appropriate
BIL insulation for the voltage being used. L type cores are used when
a DC offset is present, see BH curves.
