CST Series Heat Spreader

Minoru CST series heat spreader / dissipation EMI shield is a low-cost thermal conduction sheet based on copper foil and newly developed high performance graphene heat conduction layer.

It is possible to make a stable connection to the adherend via the heat conductive adhesive layer. There are wide variety of thicknesses, which enhances the design flexibility when used in combination with other components.

Based on copper foil, it has high EMI shielding characteristics for wide frequency range.

CST Series Overview

Overview	MINORU® Heat Spreader shield Single-sided copper foil tape CST series is a low-profile product with high EMI shielding properties and heat spreading characteristics. CST has stable shield characteristics in a wide range from 30MHz to 3GHz.
Structure
Characteristic	* Has high processability such as die cutting. High heat dissipation characteristics in the XY directions. As it is a very thin copper foil base, it has high conformability to bent parts. * Flexible and can be attached to curved areas
Application	∗ Electromagnetic wave shield and heat dissipation of ECU etc. ∗ EMI shield for various electronic devices *LCDM EMI and light shield, driver IC heat dissipation
Specification
Environment	CST series are halogen-free products.
