Standard Silicone-Base Thermal Pads – IMTH50 Series
IMTH50 series thermal pads have a high conductivity of 5.0 W/m*K and is available in 0.5 mm to 10 mm thicknesses.
Features
KITAGAWA INDUSTRIES America’s IMTH series, silicone-based thermal pads are popular items for many applications such as cell phones, laptop, routers, network servers etc.
KITAGAWA INDUSTRIES America offers a wide variety from 1.0 W/m*K up to highest 7.0 W/m*K in thicknesses from 0.5 mm up to 20 mm.
They are also the superior and longer lasting solutions in comparison to thermal grease. Thermal grease or paste can be very difficult to handle. Its liquid form makes it messy to apply, and unless one completely covers an entire surface evenly, areas with less thermal grease will have less performance.
Part Number Example: IMTH50-010
