Description Of The Varistor SMD
The so -called patch pressure -sensitive resistance is an ESD protection component for over -electrostatic protection. The response time NS level is slower than the TVS diode. It is faster than the ceramic gas discharge tube. , PS2, VGA, audio), laptop, set -top box, MP3 player, DVD player, and docking system. There are many types of pressure -sensitive resistance, complete models, and model names are generally represented by packaging. The packaging of the patch pressure -sensitive resistance can be represented by two sizes. One British code and the other are the rice -made code. They are all represented by 4 digits.
AMPFORT Electronics has independently developed, produced, and sold patch -sensitive resistance, which is represented by the British code. At present, the number of patch -sensitive resistance in the market is: The specific models are: 0603, 0805, 1206, 1210, 1812, 2220, 3220, etc.
