Features and Benefits

• Thermal conductivity: 0.8 W/m-K

• Conformable, low hardness

• Enhanced puncture, shear and tear resistance

• Electrically isolating

Gap Pad VO Soft is recommended for

applications that require a minimum amount

of pressure on components. Gap Pad VO

Soft is a highly conformable, low-modulus,

filled-silicone polymer on a rubber-coated

fiberglass carrier.The material can be used

as an interface where one side is in contact

with a leaded device.

Note: Resultant thickness is defined as the final gap

thickness of the application.
