Common Mode Chokes For DC and single-phase AC power lines Single-phase FM coils Single-phase FM coils FM series single-phase common mode chokes with FT-1KM KN cores (p. 30) are compact in size and have excellent electromagnetic noise suppression properties. Table 3. Standard Specifications Item Specification Rated voltage AC250V or DC250V Insulation voltage rating AC1.5kV for 1min. or AC1.8kV for 3 sec. Insulation resistance Over 100M after applying DC500V for 1 min. Insulation grade Class E (120 C) Temperature rise 45 C * Operating temperature range -40 C - +120 C (including temperature rise) * 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. Table 4. Product code, part number and specifications (A) MIN. MIN. (mm) MAX.
