miniature screened, open frame
3.5 kV, 3.5A
4 series
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.
