CotoMOS® CT128/CS128
e CT128 and CS128 feature high current switching capability to 4.5A with a low
on resistance of 0.05Ω Maximum. Designed for ATE, Controls, or Measurement and
Instrumentation applications the CotoMOS® relay is capable of handling 40V load
conditions. If your requirements are dierent please contact your Coto Applications
Engineer for assistance through www.cotorelay.com or email us at
