Additional Details

The specific parameters for this varistor include:

• Varistor Voltage: Approximately 225V (This is an estimated value as "140K" implies a voltage around 140Vrms, which is then converted to peak voltage for surge protection. The exact clamping voltage characteristics will be detailed in the datasheet.)
• Maximum Surge Current: This value can vary but is typically in the range of several kA (kilo-Amperes) for a single 8/20 μs pulse (refer to the datasheet for precise values).
• Operating Temperature: Typically -40°C to +85°C (consult datasheet for the exact range).
• Disc Size: The physical size of the varistor disc affects its energy handling capability. Datasheet will provide the exact dimensions.

It's crucial to consult the official datasheet from TDK Corporation for precise electrical characteristics, surge current ratings, clamping voltage curves, and other relevant parameters before using this component in any application. The datasheet will provide detailed information necessary for proper circuit design and ensuring adequate surge protection.
