B10 RF Relays
Ball Grid Array Relays
Coto's Ball Grid Array (BGA) construction offers a breakthrough in
reed relay performance. This patented technology
1
allows for shorter
RF paths in a controlled 50
environment to minimize signal
attentuation. The designer is now able to switch or pass signals with
wider bandwidth and faster rise time than alternative technologies.
This is particularly important in Mixed Signal IC testers. BGA packag-
ing allows relays to be integrated easily on boards designed for surface
mount processing.

B10 RF Relays
NOTES:
1
All parameters specified per EIA/NARM standards
for dry reed relays, # RS-421 and RS-436, if a
suitable parametric standard exists.
2
Unless otherwise noted, all parameters are specified
at 25C and 40% RH.
3
Life expectancies based on characteristic life
(63.2% failure) calculated from the 2-parameter
Weibull distribution. Contact resistance >2.0
defines end of life.
4
Frequency at which the difference between output
and input signal amplitude exceeds -3dB. (Direct
wired using 50
coaxial cable.)
ENVIRONMENTAL RATINGS:
Storage Temperature: -35C to +100C.
Operating Temperature: -20C to +85C.
Vibration: sinusoidal vibration with an amplitude of
10G over a 10Hz to 2000Hz frequency range shall
not cause a closed channel activated at the nominal
coil voltage to open, not an open channel to close.
Max Soldering Temperature: 226C (438F) max for
1 minute dwell time. Temperature measured at a
relay ball termination.
