The world's leading passive component manufacturer, Guoju Group, has launched the new "anti-vulcanization high-power anti-surge resistance" -AS series for vehicles, mainly used in high-power and high-pulse requirements exposed to high-pollution environments, including industrial control systems, converters, inverters, power supplies, printing equipment, chargers/charging equipment, automotive electronics, communication base stations, etc. And other electronic equipment used in areas with high sulfur gas concentration, such as hot springs and mining areas. Automotive applications include power transmission, engine control units, infotainment systems, chassis, driving information modules, lighting systems and electric vehicle charging modules.

Compared with the AF series of Guogu general anti-sulfur thick film resistance, AS series has both anti-sulfur and anti-surge, and has a high reliability, can meet the more stringent product applications. According to the international standard ASTM test, AS series meet the most stringent test standards, has excellent vulcanization resistance characteristics; The unique anti-surge design can withstand high pulses in the circuit, and provides additional triple and quadruple power specifications, so it can operate in high power environments. At present, the AS anti-vulcanization high-power anti-surge resistance developed by Guogushi is available in size 0603/0805/1206 and has been mass-produced.

In order to achieve the purpose of sulfur resistance, some suppliers have introduced the use of gold internal electrode anti-sulfide resistance, but this way of manufacturing cost is very high. In view of this, AS series of internal electrode added other special elements, optimize the structural design, greatly improve the product vulcanization resistance, anti-pulse ability, and provide highly competitive product prices. Due to the increasing concern of global environmental degradation, the company will continue to develop products for harsh environment applications to meet the needs of customers, following the existing AH(anti-sulfur high-voltage resistance) and AS(anti-sulfur and anti-surge) series.
