ALS36 85°C MECHANICAL DATA Mounting position The capacitor can be mounted in any position so long as the safety vent can operate. It is possible for some electrolyte to be expelled. As this is a conducting liquid, suitable precautions should be instigated by the system designer to avoid secondary short circuits. The capacitors are designed to be mounted in free air and are not suitable for submersion in liquid. Vibration 10Hz to 55Hz at 0.75mm or 10g for 3x2hrs duration. Except 220mm long cans 10Hz to 55Hz at 0.35mm or 5g for 3x0.5hrs duration. Insulating resistance > 100 Mohms at 100V d.c., across insulating sleeve. Voltage Proof > 2500V d.c., across insulating sleeve. Safety vent A safety vent for over pressure is featured on terminal deck. This is in the form of a rubber plug designed to relieve build up of internal pressure due to over stress or catastrophic failure. OPERATIONAL DATA The failure rate is derived from our periodic test results. The failure rate ( λ R) is therefore only given at test temperature for life tests. An estimation is also given at 40°C. The expected failure rate for this capacitor range is based on our periodic test results for capacitors with structural similarity. Failure rate is frequently quoted in FIT (Failures In Time) where 1 FIT = 1 x 10 -9 failures per hour. Failure rates include both catastrophic and parametric failures T a Failure rate per hour 85°C 250 FIT 40°C 12 FIT RELIABILITY Operational Lifetime Please see separate BHC application notes TD003 for calculating operational life expectancy under customer specific conditions.
