Dual Function Noise Suppression Thermal Pad : CPLK Series

Noise suppression thermally conductive sheet

  • CPLK’s low permittivity 14.6/1MHz has a significant effect on noise reduction

  • Low-dielectric thermally conductive sheet helps to reduce noise in GHz bands, which occurs by heat sink’s resonance phenomena

  • Silicone-free generates no siloxane gas and oil bleeding
