Gap Pad
®
VO is a cost-effective, thermally
conductive interface material.The material
is a filled, thermally conductive polymer
supplied on a rubber-coated fiberglass
carrier allowing for easy material
handling.The conformable nature of
Gap Pad
®
VO allows the pad to fill in air
gaps between PC boards and heat sinks
or a metal chassis.

. 3) The ASTM D5470 test fixture was used. The recorded value includes interfacial ther-
mal resistance. These values are provided for reference only. Actual application performance is directly related to the sur-
face roughness, flatness and pressure applied.
TYPICAL APPLICATIONS INCLUDE
• Telecommunications
• Computer and peripherals
• Power conversion
• Between heat-generating semiconductors or
magnetic components and a heat sink
• Area where heat needs to be transferred to a frame,
chassis, or other type of heat spreader
CONFIGURATIONS AVAILABLE
• Sheet form and die-cut parts
