Abstract
On the surface of a ceramic sinter, at least an external electrode for input, an external electrode for output, and external electrodes for grounding are disposed, and the ceramic sinter includes an inductor electrically connected to the external electrode for input and external electrode for output, and a varistor electrically connected to the external electrode for input and external electrodes for grounding. By connecting the inductor to the signal line of the circuit of an electronic appliance and connecting the varistor between the input side of the signal line and the ground, electrostatic discharge pulses of about 0.5 to 2 nanoseconds can be suppressed efficiently.
