U91F Specifications - Snap Mount Rated Voltage Range 350 to 500VDC Capacitance Range 120 to 2,700 F Capacitance Tolerance 20% ( M ) at 20 C, 120Hz Leakage Current I = 3 CV ( A) or 3mA, whichever is smaller, after 5 minutes at 20 C. Where I = Max. leakage current ( A ), C = Nominal capacitance ( F ) and V = Rated voltage ( V ) Rated Voltage ( V ) Tan ( DF ) Max. 350 - 400 0.15 420 -500 0.20 Dissipation Factor ( Tan )At 20 C, 120Hz Rated Voltage ( V ) Z( 25 C) / Z ( 20 C) 350 -500 8 Low Temperature Characteristics At 120Hz, impedance ( Z ) ratio between the 25 C value and 20 C value shall not exceed the values given below. Rated Ripple Current Multipliers Ambient Temperature ( C) 65 C 2.82 85 C 1.73 105 C 1.00 Frequency (Hz ) DC Rated Voltage 350 - 450V 500V 50Hz 0.77 0.70 120Hz 1.00 1.00 300Hz 1.16 1.16 1kHz 1.30 1.30 10kHz 1.41 1.41 100kHz 1.43 1.43 Shelf Life The following specifications shall be satisfied when the capacitors are restored to 20 C after exposing them for 1,000 hours at 105 C without voltage applied. The rated voltage shall be applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than 48 hours before the measurements. Capacitance change: ≤ 20% of initial measured value Tan (DF) : ≤ 150% of initial specified value Leakage current : ≤ initial specified value Endurance (Load Life) The following specifications shall be satisfied when the capacitors are restored to 20 C after subjecting them to DC voltage for 5,000 hours at 105 C with the rated ripple current applied. The sum of the DC voltage and peak AC voltage must not exceed the full rated voltage of the capacitors. Capacitance change: ≤ 20% of initial measured value Tan (DF) : ≤ 200% of initial specified value Leakage current : ≤ initial specified value |
