MLP Capacitors, 85°C Flatpack

12.5mm Pitch, High Energy Density and Near Hermetic Seal

Type MLP flatpack capacitors rated to 85 °C, encased in a grade 1100 aluminum case are versatile components for military and aerospace applications. Their high capacitance density in a 12.5 mm pitch permits use in most rack mounting applications. The box shape encourages efficient stacking into module assemblies. Their broad, flat sides make heatsinking simple and effective. The unit’s nearly hermetic seal and high-purity materials assure extremely long life. The MLP has over twice the energy density of a 1⅜-diameter, 105 °C screw-terminal capacitor. It has about four times the energy density of a bank of ½” diameter 105 °C capacitors. Compared to the space lost with the round-can shape of ordinary capacitors, the flatpack package amplifies the space savings by 27%. The high-energy storage and convenient low-profile box shape of these flatpack capacitors make them right for low-profile board applications and for stacked assemblies. Power holdup is the most popular application for equipment as diverse as shipboard antennae and power holdup in the radio system for jet fighters.


  • Low-profile replacement for snap-ins
  • Double the ripple capability with a heatsink
  • Nearly hermetic welded seal assures 50-year lifer
  • Withstands more than 80,000 feet altitude
  • –55 °C to +85 °C ≤250 Vdc; -40 ºC to +85 ºC ≥300 Vdc

Applications Include:

Wet-tantalum replacement, military power supplies, power-holdup for F16 and a ground-to-satellite phone

    3 CELL DSF & DGH

    Three-cell devices offer greater energy potential and power output than single or dual-cell parts in standard PCB layouts

    3-cell DSF & DGH capacitors provide very fast power discharge that cannot be matched by conventional capacitors or batteries. That large capacity makes it possible to support brief power interruptions, supplement batteries, or even be used in place of batteries in many applications.

  • TYPE MXT, X2, EMI/RFI Suppression Capacitors, Harsh Environment
    Released Nov, 2023

    TYPE MXT, X2, EMI/RFI Suppression Capacitors, Harsh Environment

    Type MXT Series Metallized Polypropylene Film Capacitor, designed to suppress conducted electromagnetic/radio frequency interference (EMI/RFI) at a circuit’s power input. These capacitors are perfect for use in harsh environments having met the demanding 85/85 THB (Temperature, Humidity, Bias) test requirements. Class X2 capacitors, like the MXT, are typically connected across the AC input to prevent interference from spreading through power lines or other devices on the same circuit.
