1 / 9 page JUNE 2015 ■ 91 Medium Power Film Capacitors FAI (RoHS Compliant) TUNING ELECTRICAL CHARACTERISTICS Capacitance range Cn 110nF to 60μF Tolerance ±10% Rated AC voltage 200 to 650 Vrms Series parasitic inductance < 5 nH Test voltage between terminals @ 25°C 1.2 Vrms 50/60 Hz 10s Dielectric Polypropylene The FAI series uses metallized polypropylene dielectric specifically designed for very high reactive power. The FAI's special design gives to this series a very low level of stray inductance. APPLICATIONS These capacitors have been designed principally for: low and medium frequency applications (10 kHz to 500 kHz) MAXIMUM WORKING TEMPERATURE (HOT SPOT) +85°C: Hot spot temperature must be calculated as function of power dissipation. 10 00 10 00 0 10 00 00 10 00 00 0 60 70 80 90 Theoretical life time vs hot spot temperature Hot spot temperature ( ∞C) HOT SPOT (THERMAL) CALCULATION See Hot Spot Temperature page 3. You can calculate the maximum operating (hot spot) tem- perature of this capacitor in the following manner: Polypropylene has a constant loss factor (tg δ0) of 2x10-4 irrespective of temperature and frequency (up to 1 MHz). The loss factor of the capacitor is made up of the sum of two components. The first represents electrical losses (tg δ0 = 2.10-4) and the second represents Joule effect in the connection and foils: Rs.C.2 πF. For all applications, the temperature in the hot spot capacitor must be lower than 85°C. Heating calculation of hot spot capacitor: FAI1 FAI2 FAI3 θ hot spot = θ terminals + (tgδ0.Q + Rs.(Irms)2).Rth Heating calculation of hot spot capacitor: FAI6 θ hot spot = θ water + (tgδ0Q + Rs.(Irms)2).Rth With: tg δ0 = 2.10-4 Q in Var Rs in Ohms Irms in Amperes Rth in °C/W (water flow = 10 dm3/minute) Note: The life time depends of hot spot temperature, see following curve.
