What is “ESD Suppressor , High withstanding type”
ESD suppressor corresponding to ESD standards for Automotive electronics(ISO10605)
-
- Excellent ESD withstanding due to discharging between electrodes inside the cavity
- -corresponding to ESD standards for automotive electronics (ISO10605), air discharge 25kV
-
- Low capacitance (0.1pF)
- -Do not degrade signal quality of High-speed data line and Insertion loss of high frequency circuit
-
- High rated voltage (DC 50V)
- -Small risk of malfunction and transmission error caused by emission noise and conduction noise
