五、Product description


     

The thermal conductive silica gel sheet is used to fill the air gap between the heating device  the heat sink  the metal base. Its flexible  elastic characteristics enable it to cover the very uneven surface. Heat is transferred  the separating device  the whole PCB to the metal shell

on the diffusion plate, thereby improving the efficiency  service life of the heating electronic components.


六、Storage

Storage validity: 12 monthsStorage conditions: cool  dry place under normal temperature  
Relative humidity: RH < 70%
