The CN2220K50G varistor has specific voltage characteristics, including the varistor voltage (the voltage at which the varistor starts to conduct significantly) and the maximum clamping voltage. The energy handling capability (joules) is also an important parameter for selecting the appropriate varistor for a given application. Refer to the EPCOS (TDK) datasheet for detailed specifications, including surge current ratings, capacitance values, and operating temperature ranges. Proper soldering techniques are essential for reliable surface mount assembly.
