click here to see hardware and mounting options Type DCMC 85 C High Capacitance, Screw Terminal, Aluminum Highest Capacitance Screw Terminal Type With more capacitance and often more ripple-current capabilty than the best-value Type 3186 capacitor, the Type DCMC capacitor is the better choice for high-capacitance, power supply filters and energy storage applications such as welding equipment,UPS systems and computer hold-up power. The extended cathode foil of the DCMC assures cool operation with heatflow from the capacitor element to the can. Highlights - Highest capacitance value - Right for Power Supply and UPS systems - Thermal-Pak extended cathode construction Specifications Temperature Range 40 C to +85 C Specifications Rated Voltage Range 6.3 Vdc to 550 Vdc Capacitance Range 110 F to 2.7 F Capacitance Tolerance 10% +75% 100 Vdc 10% +50% 160 Vdc Leakage Current 6 CV A, 6 mA max, at 5 min 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 kHz 50 Hz 60 Hz 120 Hz 360 Hz 1 kHz 5 kHz & up 1 3/8 & 1 3/4 Diameters 0.92 0.94 1.00 1.05 1.10 1.10 1.12 6.3 to 160 V 0.80 0.85 1.00 1.17 1.30 1.30 1.32 200 to 350 V 400 to 550 V 0.78 0.83 1.00 1.20 1.35 1.36 1.40 2 & 2 1/2 Diameters 0.93 0.95 1.00 1.04 1.07 1.11 1.12 6.3 to 160 V 0.81 0.87 1.00 1.13 1.20 1.24 1.26 200 to 350 V 400 to 550 V 0.79 0.83 1.00 1.17 1.26 1.30 1.34 3 & 3 1/2 Diameters 0.95 0.96 1.00 1.02 1.04 1.05 1.05 6.3 to 160 V 0.85 0.88 1.00 1.08 1.12 1.14 1.17 200 to 350 V 400 to 550 V 0.82 0.84 1.00 1.13 1.20 1.24 1.27 Low Temperature Characteristics Impedance ratio: Z Z 20C +25C 20 (6.310 Vdc) 8 (1650 Vdc) 4 (63100 Vdc) 3 (150550 Vdc) Endurance Life Test 2000 h full load at 85 C Capacitance 20% ESR 200% of limit DCL 100% of limit Shelf Life Test 500 h 85 C Capacitance 100% of limit ESR 100% of limit DCL 100% of limit Vibration 5 to 55 Hz, 0.06 and 10 g max, 1.5 h each of 2 axes Regulatory Information CDM Cornell Dubilier 140 Technology Place Liberty, SC 29657 Phone: (864)843-2277 Fax: (864)843-3800 Type DCMC 85 C High Capacitance, Screw Terminal, Aluminum Highest Capacitance Screw Terminal Type Part Numbering System DCMC 472 U 400 DC 2 B S Type Capacitance Tolerance Voltage Case Code Insulation Terminal Can Style 0= None A = Low Post Blank= 100 = 10 F M = 20% 6R3 = 6.3 Vdc 1= Polyester B = High Post Standard 101 = 100 F U = 10%+75% 063 = 63 Vdc 2= PVC D = High Current, Can 492 = 4900 F T = 10%+50% 400 = 400 Vdc Low Post S= Stud 433= 43,000 F E = High Current, Bottom Polyester insulation is not available for 3.5-inch diameter units.
