Type MLS 125 °C Flatpack, Ultra Long Life, Aluminum Electrolytic
Now Available with High Vibration and High Reliability Options
Encased in rugged stainless steel, the MLS is perfect for high reliability
military systems and applications operating above 85 °C. For our
highest performing 125 °C Flatpacks, choose type HVMLS available in
a special stainless steel case for high vibration applications up to 50g.
Specify type HRMLS for high reliability Flatpacks which are subjected
to MIL level burn-in processes to ensure established reliability.

Vibration
Standard MLS Flatpack: 10g
Mounting: Vibration capability is dependent upon mounting restraint. The
optional welded mounting tabs, alone, are not capable of sustaining the high
vibration levels.
