VThe 10D431K is an electronic component manufactured by COVV, and consists of two Varistors with 350V and 710V rating, 2.5KA power discharge capability and a Through Hole RoHS design. Varistors are two-terminal semiconductor devices which act as variable non-linear resistors, designed to limit and clamp transient voltages. The 350V and 710V ratings indicate the maximum allowable operational voltage for the Varistors. The 2.5KA power discharge capability indicates that the Varistors can absorb and safely dissipate up to 2.5kA of electric current. The Through Hole RoHS design involves drilling a hole into the component in order to mount it on a printed circuit board, and the RoHS compliance indicates that the component meets specific emission levels of hazardous materials.
