The TVR10621 is a varistor manufactured by TKS. Varistors, also known as voltage-dependent resistors (VDRs), are electronic components used to protect circuits from voltage surges and transient events. When the voltage across the varistor exceeds a certain threshold, its resistance rapidly decreases, diverting the excess current away from sensitive components.
