关于N4700 材料
N4700陶瓷电容是近年研发成功的一种新型陶瓷,是产品中广泛使用的陶瓷材质,相对于其它I类陶瓷其介电常数大,适合于做容量较大的电容,其具有耐压更高,介质损耗小于0.2%,比一般II类陶瓷低很多;绝缘电阻大于200000MΩ,频率特性好,温度系数好,承受电流大,在温度从-25℃到+85℃时容量变化+/-28%,寿命长,其使用寿命在10年以上。
◆注意事项PRECAUTIONS
(1)运输和储存
•不要放置在有毒气体,如硫酸,盐酸,硝酸等。
(2)在操作过程中
•避免过多的影响,如坠落造成。
•不要再机终端。
•当电容器用于高速脉冲,如激光,确保外加电压(峰 - 峰值电压),电容器的额定规格内。
• Do not transport or store where the capacitor will be exposed to high temperature or high humidity.
• Avoid excessive impact such as that caused by falling.
• Avoid contact with electrolytes such as perspiration. Do not touch with bare hands.
• Do not apply solder to stud terminals.
(3) Usage
• Make sure that the capacitor is not exposed to radiant heat from cham
