Common Mode Chokes
For three-phase AC power lines
●Three-phase FN coils
FN coils, using FT-3KM cores are compact three phase
common modes chokes having excellent RF noise
suppression properties for rated current over 100 Amperes.

• The above specifications are in accordance with Electrical Appliance and Material Control Law, UL, CSA and IEC standards.
• No Ozone Layer Depleting Chemicals are used in these products or in their manufacturing process.
* Note 1: The temperature rise in Table 1 is a projected value based on temperature increase by the heat from DC resistance of the coil when the rated current (DC
or 50/60Hz) in Table 2 is conducted.
* Note 2: The temperature rise is affected by the mounting condition on the circuit board and the amount of harmonic distortion on the load current. Please make
sure that the temperatures of the coil and the terminals are not exceeded the operating temperature range.
