SPST Reed Relays
DESCRIPTION
The MEDER CRR Series Reed Relay is a low-profile
device made with a ceramic case that exactly matches
the thermal coefficient 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.
Capable of withstanding reflow-soldering operations
up to 260°C, the relay uses no internal solder and 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 co-planarity issues. Insulation resistance
typical to all points is >1014 Ohms.
