click here to see hardware and mounting options Type 3191, Aluminum Electrolytic Screw Terminal Screw Terminal Capacitors for Power Output Filtering The low ESR of Type 3191 capacitors makes them a great choice for output filtering in switching and audio power supplies. Its 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 Temperature Range 40 C to +85 C Rated Voltage Range 7.5 Vdc to 55 Vdc Capacitance Range 2700 F to 150000 F Capacitance Tolerance 10 to + 30% 10 to +50% 20% Leakage Current 6CV A (6 mA max.) at 5 minutes Ripple Current Multipliers Ambient Temperature 45 C 55 C 65 C 75 C 85 C 2.24 2.00 1.73 1.41 1.00 Frequency 10 60 Hz 120 Hz 300 Hz 1000 Hz kHz 16 100 V 0.90 1.00 1.15 1.25 1.30 200 500 V 0.90 1.00 1.25 1.40 1.50 Low Temperature Characteristics Impedance ratio: Z Z 20 C +25 C 8 (1650 Vdc) 4 (63100 Vdc) 3 (150500 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 Capacitance: 5% no visible damage or leakage *15 g if rilled construction RoHS Compliant CDM Cornell Dubilier 140 Technology Place Liberty, SC 29657 Phone: (864)843-2277 Fax: (864)843-3800 Type 3191, Aluminum Electrolytic Screw Terminal Screw Terminal Capacitors for Power Output Filtering Part Numbering System 3191 B P A1 BA 153 T 7R5 Terminal Insulation Type Capacitance Case Code Tolerance Voltage Construction* 153=15000 F A=high post P=0.008 PVC M= 20% 7R5=7.5 Vdc A1=potted B=low post H=0.012 PVC 223=22000 F S= 10 +30% R1=rilled 020=20 Vdc D=high current N=none T= 10 +50% 272=2700 F S1=stud & potted low post with mounting U= 10 +75% T1=stud & rilled** K=high current R=0.008 PVC * Construction code is also a sequence number, e.g., A1, A2,---,A9, B1,B2,---, for customer specifications.
