DBT70510 Datasheet, PDF (1/2 Pages) Cynergy3 Co – Low Contact Resistance

D series
TTM
high voltage reed relays
15kV, 50W
Very high isolation voltages, up to 15kV, are
achieved through the use of high vacuum reed
switches with either Rhodium or Tungsten contacts
and make these relays suitable for high reliability
applications such as cardiac defibrillators, test
equipment and high voltage power supplies.
The Rhodium contacts have low contact resistance
while the Tungsten contacts can switch higher
voltages.
Printed Circuit Board (PCB) or Panel mount, via
nylon studs, versions are available.
Connection options include PCB, solder turret tag,
flying lead and Faston* style Spade Terminals.
Available as Form A (SPNO) or Form B (SPNC)
contact configurations.
