DESCRIPTION
The MEDER CRR Reed Relay Series is a low-prole
device made with a ceramic case that exactly matches
the thermal coefcient of expansion of the Reed Switch
glass and the reed lead to eliminate any potential
packaging stress. This Reed Relay is the smallest in the
industry and switches into the billions of operations.
This Relay has 1 µV typical thermal offset. Measuring
only 8.6 mm x 4.4 mm x 3.4 mm, the leadless design
eliminates skewing of leads and coplanarity issues.
Insulation resistance typical to all points is >1014 Ohms.
