20D431K product description

         1. The working voltage is AC 275V or DC 350V, which can adapt to different power supply environments.

         2. The varistor voltage is 387V~473V. When the voltage exceeds this range, its resistance will drop sharply, thus shunting the overvoltage to the ground or neutral wire.

         3. The clamping voltage is 710V, that is, when a transient voltage occurs, it can limit the output voltage below 710V, thereby protecting the subsequent circuit.

         4. The peak surge current is 6.5kA, that is, it can withstand the maximum pulse current of 6.5kA without damage.

         5. The absorbed energy is 190J, that is, it can absorb the maximum pulse energy of 190J without damage.

         6. The package type is in-line, the size is Φ23.00 x 6.70mm, which can be easily installed on different devices.

         7. With CE certification, it meets the requirements of RoHS and RoHS phthalates, which can guarantee the quality and safety of products.

20D431K product application

         1. Power supply equipment: 20D431K can be used to protect various power supply equipment, such as switching power supply, UPS, inverter, etc., to prevent damage to equipment caused by transient overvoltage caused by lightning strikes, switch trips, short circuits, etc.

         2. Consumer electronics products: 20D431K can be used to protect various consumer electronics products, such as TVs, audio, DVD, game consoles, etc., to prevent transient overvoltage caused by plugging and unplugging, electrostatic discharge, inductive coupling, etc. cause damage.

         3. Industrial control equipment: 20D431K can be used to protect various industrial control equipment, such as PLC, sensors, actuators, etc., to prevent transient overvoltage caused by environmental factors such as high noise, high temperature, and high humidity on the industrial site. cause damage.
