Additional Details:

The V385LT40CX2645 is a leaded varistor with a voltage rating designed to clamp voltages at a specific level, preventing damage to downstream components. Varistors are non-linear resistors that exhibit a dramatic decrease in resistance when the voltage exceeds a certain threshold. This allows them to divert surge currents away from sensitive circuitry. This particular model is designed to handle high surge currents, making it suitable for applications where exposure to large transient events is possible. The varistor's compact design facilitates integration into various PCB layouts.

Key Specifications:

• Maximum continuous operating voltage: Typically around 385V DC or AC
• Surge current capability: Varies with pulse width and number of pulses.
• Operating Temperature Range: typically -40°C to +85°C.
