Additional Details:

The CT1812K75TELEG2 has a maximum surge current rating of 700A. The '1812' in the part number indicates the EIA case size, which is 18 x 12 mils. The varistor voltage is typically around 75V. This device offers bi-directional clamping characteristics, meaning it provides surge protection regardless of the polarity of the transient voltage. This varistor is commonly used in applications where space is a constraint but high surge protection is required. The operating temperature range is typically between -40°C to +85°C. Its construction utilizes a ceramic body to ensure optimal performance and durability.
