Voltage Protection Out of Range

This product is called GDT (Gas Discharge Tube) which is currently the best mean to protect electronic circuits against out of range voltage.

GDT Type Test
Nominal DC Spark Over Voltage 230 ± 20%
Impulse Spark – Over Voltage @ 1 KV / µs < 700 V
Nominal Impulse Discharge Current 8/20 µs 5KA
Insulation Resistance (100V) AS ITU-T K.12 1000MΩ
Capacitance AS PER ITU-T K.12 ≤ 20PF

Current Protection Out of Range

Below product is placed on the piece called PTC (Positive Temperature

 Coefficient) its name considering which suggests an increase in temperature caused by the unauthorized flow of electrical resistance and increases rapidly and impedes the flow.

PTC Type Test
Maximum Nominal Current at 20 °C 120 mA
Typical Switching Time for Current Protection (500mA/25 °C) ≤ 10 s
Nominal Decoupling Resistance at 20 °C ≤ 10Ω
