Abstract: The properties of varistors play an important role in the stability of electronic complete machines and equipment. Axial varistors are required to be used in electronic complete machines and electronic equipment. They have the functions of overvoltage protection, noise elimination, amplitude limiting, lightning protection, and semiconductor device protection and so on. They are important components of various military electronic products such as electronics, communications, information, military and aerospace. The external dimension design, limiting voltage and energy tolerance of the axial elicitation chip varistor are studied. The function, manufacturing process and current design status of the axial elicitation chip varistor are reported. The use requirements and application scenarios of the axial elicitation chip varistor are investigated. The key technologies of the axial elicitation chip varistor, such as tape casting film preparation control, rubber discharge firing process curve, are studied.
Keywords: chip varistor; axial elicitation; low clamping voltage; nonpolarity
