European components when current rating is increased by monitoring the current temperature of the metal conductor determined. When the temperature of the metal pin is higher than the ambient temperature of 45 ℃, surveyors will be current at this time as the rated current value (or the maximum current value) of the device. Another IEC specifications are permitted current value, which is 80% of the maximum current. In contrast, UL standards will allow 90% 30 ℃ current value when the metal conductor temperature higher than the ambient temperature as the current nominal value of the device. With high-quality corporate globalization telephone terminals, the need to design a system in global sales of high-quality terminals Which is good service, system designers more and more often used in other countries producing products terminals. As the European nominal value measurements, so that the device is lower than the nominal value is used in the design is common practice in Europe. However, where there are high-quality terminals, many American designers are not familiar with this concept, if not understand the differences between the various standards in the design process will be difficult. Which high-quality terminal concessions, high-quality terminals, Xu Chong-electronic products factory by the Dongguan Shijie Xu Chong-electronic products factory provided. Dongguan Shijie Xu Chong-electronic products plant (chuangxs.1688.com) (www.chuangxs.1688.com) strong, credible, connectors, and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
