摘要
通过计算机通信接口芯片的过电压耐受能力试验、电路分布电容对计算机通信的影响试验,提出了计算机通信接口过电压保护器设计时,主要应考虑被保护器件的过电压耐受能力与电路最大接入电容。
Through the over-voltage tolerance test of communication interface chip and the test of effect of distributed capacitance on communication, the paper proposes that the over-voltage tolerance ability of apparatus protected and circuit maximum capacitance should be considered when communication interface SPD is designed.
