CMS1210 82v-180v低压贴片压敏电阻 1210陶瓷压敏

The Ceramic Micro-Surge Protection Device (CMS) is manufactured from semiconducting ceramics which offer  rugged protection and excellent transient energy absorption in a small SMD package. These devices are designed to  suppress a variety of transient events, including those speified in IEC61000-4-2, IEC61000-4-5 and other standards  used for Electromagnetic Compliance (EMC).  

These devices are available in ceramic leadless chip form, eliminating lead inductance and assuring fast speed of  response to transient surges. In addition, The CMS transient suppressors have temperature independent  suppression characteristics, affording protection from -55℃ to 125℃, which is much better than suppressors based  on silicon semiconductor technology.  

The CMS-P Series is specially designed for AC power-lines protection applications. It features a very high current  protection capability with a very small size, also a very fast response thus a ultra low clamping voltage. These  characteristics make CMS-P Series devices the best replacement of TVS and improvement of metal oxide (MOV) in  high working voltage applications.
