Additional Details

The CU4032K14G2 has a typical capacitance of 14 pF. It is designed for reflow soldering processes. The operating temperature range is typically -55°C to +125°C. The varistor material is a ceramic semiconductor with non-linear voltage-current characteristics. It presents a high resistance at normal operating voltages and a very low resistance during transient events, effectively clamping the voltage and diverting the surge current. The bidirectional characteristic allows it to protect from both positive and negative voltage spikes.
