Type MLSG Flatpack, 5000 hr 125 C, Aluminum Electrolytic Available with High Vibration and High Reliability Options With over 5000 hrs of DC life at rated voltage, 125C, type MLSG is our longest life steel-cased Flatpack capacitor. For systems requiring the highest life expectancy, type MLSG is the best choice. Enhance the reliability of your system even further by specifying type HRMLSG for a MIL-level burn-in. This series is also available in a high vibration package up to 50gs by specifying type HVMLSG.

The Standard MLSG Flatpack: 10g optional welded mounting tabs, alone, are not capable of sustaining the high Type HVMLSG Flatpack 1.5 and 2.0 case length, 50g vibration levels. Type HVMLSG Flatpack 2.5 and 3.0 case length, 30g To achieve the high vibration levels as published on right, additional mounting restraint is required.

Amplitude The specimens shall be subjected to a simple harmonic motion having an amplitude of either 0.06-inch double amplitude (maximum total excursion) or peak level specified above (XXg peak), whichever is less. The tolerance on vibration amplitude shall be 10 percent. Frequency Range The vibration frequency shall be varied logarithmically between the approximate limits of 10 to 2,000 Hz. Sweep Time and Duration The entire frequency range of 10 to 2,000 Hz and return to 10 Hz shall be traversed in 20 minutes. This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 12 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met. High Reliability Test/Burn-in Established Reliability capacitors shall be subjected to a minimum of 100 percent of the dc rated voltage at 85 C for 48 hours minimum but not to exceed 96 hours. During this test, capacitors shall be adequately protected against temporary voltage surges of 10 percent or more of the test voltage. After burn-in, the capacitors shall be returned to room ambient conditions and the dc leakage, capacitance, and ESR shall be measured with respect to specified limits.

Air Cooled The ripple currents in the ratings tables are for 85 C case temperatures. For air temperatures without a heatsink use the multipliers Ambient Temperature, No Heatsink. Heatsink Cooled Temperature rise from the internal hottest spot, the core, to ambient air is 2 T = I (ESR)(cc + ca), recommended max T of 30 C where cc is the thermal resistance from core to case and ca from case to ambient. To calculate maximum ripple capability with the MLS attached to a heatsink use the maximum core temperature and the values for cc. Example As an illustration, suppose you operate an insulated MLSG332M060EB1C in 65 C air and attach it to a commercial heatsink with a free-air thermal resistance of 2.7 C/W. Use a good thermal grease between the MLS and the heatsink, and the total thermal resistance is 2.7 + 2.2 or 4.9 C/W. The power which would heat the core to 125 C is (125 - 65)/4.9 or 12.24 W. For an ESR of 31 m, 12.24 W equates to a ripple current of 19.87 A. CDM Cornell Dubilier 140 Technology Place Liberty, SC 29657 Phone: (864)843-2277 Fax: (864)843-3800
