Technical Specifications

The B88069X4231S102 typically has a surge current capability of 20 kA (8/20 µs pulse). Its DC spark-over voltage is around 230V, but it can vary depending on the exact specifications. The impulse spark-over voltage (1 kV/µs) is designed to be low to ensure fast response to transient surges. The capacitance is typically less than 1.5 pF, minimizing signal distortion. The insulation resistance is very high, usually greater than 10 GΩ. The GDT is designed for through-hole mounting and has a cylindrical shape. The operating temperature range typically spans from -40°C to +85°C. The housing is made of ceramic material, providing excellent insulation and arc resistance.
