Electrolytic Capacitors

Decreased ambient cooling caused by very high component density often leads to premature capacitor failure; in fact, input voltage capacitors are typically the first parts to fail in a high power circuit. To function reliably in today's densely packed systems, the capacitor must be kept cool. Our Cap Coolers™ improve the performance and extend the life of 3.0" electrolytic capacitors.

Cap Coolers™

Cap Coolers™ are available in both one- and two-piece configurations. The single-piece extrusion provides maximum cooling for new applications, while the two-piece extrusion allows easy retrofitting for upgrading existing designs offering improved performance in an existing package.

  • Efficient, low-cost cooling using high conductivity extruded aluminum
  • Natural or forced convection cooling
  • Single-piece or retrofitable two-piece configurations
  • Both heat sink and mounting clamp
