Common Mode Chokes
For three-phase AC power lines
Three-phase FM-A coils
●Three-phase
FM-A coils
FM-A series three-phase common mode chokes are cost
reduced version of FM coils (P.14) that use a new
manufacturing process and new structure.

Specification
・No Ozone Layer Depleting Chemicals are used in these products or in their manufacturing process.
* Note 1: The temperature rise in Table 5 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 6 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.
