Additional Details

The 14D681K varistor is constructed from a ceramic material, typically zinc oxide (ZnO), which provides its voltage-dependent resistance characteristics. When the voltage across the varistor is below its clamping voltage, it exhibits a high resistance, allowing normal circuit operation. However, when the voltage exceeds the clamping voltage, the varistor's resistance rapidly decreases, diverting the excess current and clamping the voltage to a safe level. Key electrical specifications include the varistor voltage (680V), maximum surge current, clamping voltage, and capacitance. These parameters are crucial for selecting the appropriate varistor for a specific application. The 14D681K offers robust and reliable transient voltage suppression, making it an essential component for protecting sensitive electronic equipment.
