COTO B41-0001

B41 4-Channel RF Relays
Ball Grid Array 4-Channel Relays
The B41 is four independent form A channels in one planar quad
package. Coto’s Ball Grid Array (BGA) construction offers a breakthrough in reed relay performance. This patented technology1 allows
for shorter RF paths in a controlled 50 Ω 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. This four-inone BGA packaging allows relays to be integrated easily on boards
designed for surface mount processing.

B41 4-Channel 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 25°C and 40% RH.
3
Life expectancies based on characteristic life
(63.2% failure) calculated from the 2-parameter
Weibull distribution. Contact resistance >2.0Ω
defines end of life.
4
Frequency at which the difference between output
and input signal amplitude exceeds -3dB.
5
Maximum increase in operate voltage for any
channel when all channel coils are driven at
nominal coil voltage and with the same drive
polarity.
ENVIRONMENTAL RATINGS:
Storage Temperature: -35°C to +100°C.
Operating Temperature: -20°C to +85°C.
Vibration: sinusoidal vibration with an amplitude of
10G over a 10Hz to 2000Hz frequency range shall
neither cause a closed channel activated at the nominal coil voltage to open, nor an open channel to close.
Max Soldering Temperature: 438°F(226°C) for 1
minute dwell time. Temperature measured at a relay
ball termination.
Moisture sensitive component. Handle as
J-STD-020B level 5a.
