• Compliance with safety standards
• Easy to integrate into circuits with leaded design

Additional Details

The B72540T6300K062 is designed for higher voltage applications. When a voltage surge exceeds its varistor voltage (nominally 1000V), its resistance rapidly decreases, diverting the excess current and clamping the voltage to a safe level. The maximum continuous voltage rating of 630V AC indicates the highest voltage that can be continuously applied without causing damage or degradation. The part should be selected such that this value is not exceeded during normal operation. It provides protection by absorbing the transient energy. The 'K' in the part number usually indicates the tolerance of the varistor voltage.
