SAR405SU Datasheet, PDF (1/2 Pages) Cynergy3 Co – miniature screened, open frame 3.5 kV, 3.5A

4 series
miniature screened, open frame
3.5 kV, 3.5A
cyn er gy_{componen ts}
3.5A RF at 1-30MHz
3.5kV Isolation
Contacts Form A, B or Latching
Long Lifetime
A highly flexible, low cost package for RF
applications in the 1-30MHz band. The
use of vacuum reed switches with rhodium
contacts offers high isolation voltages, low
contact resistance and long operating
lifetime. Additional RF screening is
available to further enhance RF
performance for more demanding
applications.
Available as Form A (SPNO), Form B
(SPNC) or latching (bistable) contact
configurations with switch connections via
either PCB or flying lead.
