14. 14 Insertionloss curve (effect on signal) Insertion loss curve (effect on signal) Description The curve shows that the ESD Suppressor is ideal for the devices with high speed data transmission and electrical characteristic is very stable from 0.1 MHz to 8GHz. It enables to provide the lowest level of signal distortion. A device utilizing high speed data transmission can be effectively applied by ESD Suppressor from any frequency distortion occurred by over loading capacitance. Electrical Characteristics

15. 15 The capacitance from 100MHz~8GHz (nearly zero variation) The capacitance from 100MHz~8GHz (nearly zero variation) Description The curve shows that the a specific frequency stays at a very stable range when it passes through the 0.15pF ESD Suppressor. It means that the ESD Suppressor without any distortion by adding capacitance can effectively protect a device from electrostatic discharge and distortion of frequency when specific frequency flows into a device, because of low capacitance. ESD Suppressor safely protects your device from electrostatic discharge and reduces overflows of voltage as well. Electrical Characteristics
