B41 Series Ball Grid Array 4-Channel Relays
The B41 contains four independent form A channels in one planar quad package.
Coto’s Ball Grid Array (BGA) construction offers a breakthrough in reed relay perfor-
mance. This patented technology
1
allows for shorter RF paths in a controlled 50 Ω en-
vironment 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-in-one BGA packaging
allows relays to be integrated easily on boards designed for surface mount processing.

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 Temp: -35°C to +100°C; Operating Temp: -20°C to +85°C.
Moisture Sensitivity Level: Handle as J-STD-020B Level 5A.
Consult the Coto Technology website (www.cotorelay.com) for recommended reflow profile for SnPb Eutectic and SAC Alloys.
Vibration Exposure: Sinusoidal vibration with an amplitude of 10g over a 10Hz to 2000Hz frequency range shall not cause damage to relay.
