Temperature—What To Watch Out For
Due to the small dimensions of the devices, electrical characteristics will change with
temperature. Therefore, the operating temperature is a critical factor in their performance,
and must be stable before use.
IMPORTANT
Avoid unnecessary handling of the devices during use because your fingers
act as a heat source and may increase the temperature of the device.
