CT137/CS137
CotoMOS CT137/CS137
The CT137 and CS137 combine Coto quality and economy in an industry standard 6
pin DIP package. Both the CT137 and the CS137 offer low on resistance. The CT137
utilizes a thru hole lead configuration, while the CS137 offers a surface mount option
when the application requires it. Both relays are ideally suited to the needs of Test and
Measurement, Industrial, and Telecommunications.
