Technical content
The low ESR of Type 3191 capacitors makes them a great choice for output filtering in switching and audio power supplies. It’s available with the capacitor element potted in place for lowest cost or secured by rill, spoon shaped dimples in the side of the can. Rilled construction offers high vibration and shock withstanding and excellent heat transfer for higher ripple current. Highlights - Stud mount available - High current application - Industrial applications - Smoothing and filtering - Audio power supplies Specifications Type 3191, Aluminum Electrolytic Screw Terminal Screw Terminal Capacitors for Power Output Filtering CDM Cornell Dubilier • 140 Technology Place • Liberty, SC 29657 • Phone: (864)843-2277 • Fax: (864)843-3800 Temperature Range –40 ºC to +85 ºC Rated Voltage Range 7.5 Vdc to 55 Vdc Capacitance Range 2700 µF to 150000 µF Capacitance Tolerance –10 to + 30%; –10 to +50%; ±20% Leakage Current ≤6√CV µA (6 mA max.) at 5 minutes Ripple Current Multipliers Low Temperature Characteristics Impedance ratio: Z –20 ⁰C ∕ Z+25 ⁰C ≤ 8 (16–50 Vdc) ≤ 4 (63–100 Vdc) ≤ 3 (150–500 Vdc) Endurance Life Test 1,500 h @ full load at 85 °C ∆Capacitance ±10% ESR 200% of limit DCL 100% of limit Shelf Life Test 500 h @ 85 °C ∆Capacitance ±10% ESR 175% of limit DCL 100% of limit Vibration 10 to 500 Hz, 0.75 mm or 10 g* if less, 3 directions, 2 h ea Δ Capacitance: ±5% no visible damage or leakage *15 g if rilled construction RoHS Compliant 45 °C 55 °C 65 °C 75 °C 85 °C Frequency
