50Pcs Varistors Inline 10D431K 10D 431K 10mm Diameter Electronic Fun Kit 430V Resistor Capacitor Set

SCENE 1: When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, which is equivalent to a resistor with an infinite value. Equivalent to a switch that is off. ACCURATE AND Adopted of high quality electronic components, and accuracy process, ensure for the durability. SCENE 2: When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, which is equivalent to an infinitely small resistance, equivalent to a closed state switch. SMALL BODY: Small body, easy to install and remove. STABLE WORK PERFORMANCE: The varistor has good contact performance, ensure stable working.
