Type MLPS/MLPSR 105 °C FlatpackTM, Ultra Long Life, Aluminum Electrolytic
Type MLPS Flatpack aluminum electrolytic capacitors offer high
Very Low Profile
capacitance density in a low-profile package at 105 ºC. Their welded
seals and rugged construction provide extraordinary long-life and
reliability needed for ruggedized, commercial, and military-grade power
supplies. MLPS Flatpacks have been fully tested to 10,000 hours at
rated voltage and ripple current at 105 °C.
Highlights
• Military-grade flat electrolytics, now optimized for 105 °C applications
• Life tested to 10,000 hours @ 105 °C, Rated Vdc
• High Vibration resistance up to 20g (HV Option)
• High Reliability burn-in available (48 hrs @ Vr, 105 °C)
• Welded seal resists “dry-out,” typical of conventional electrolytics.
• Excellent capacitance retention at -55 °C

Ripple Current Multiplier (Bare Case)
Ripple Current Multiplier (PE Sleeved)
The air flow multipliers are without a heatsink and use the multipliers
at the indicated temperature. The user must also ensure the
maximum peak voltage including ripple voltage that may be applied
continuously between the terminals should be less than the rated
voltage of the capacitor to achieve the longest life.
Air Cooled
The typical ripple current capability is set by the maximum permissible
internal core temperature, maximum lead current capability of
20 Arms, and a maximum 20 ºC core rise (Not heatsinked), the
maximum peak voltage including ripple voltage applied continuously
between the terminals is less than the rated voltage of the capacitor.
In addition, the user should ensure that the peak-to-peak capacitor
voltage divided by the capacitor’s rated voltage VR should not exceed
the greater of 10% or 0.01352 × (VDC Rated / 1[VDC])1/2.
