B40 4-Channel RF Relays Ball Grid Array 4-Channel Relays The B40 is four independent form A channels in one 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 4-in-one BGA packaging allows relays to be integrated easily on boards designed for surface mount processing.

Contact resistance >2.0Ω defines end of life. 4 Frequency at which the difference between output and input signal amplitude exceeds -3dB. (Direct wired using 50Ω coaxial cable.) 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 not cause a closed channel activated at the nominal coil voltage to open, not an open channel to close. Max Soldering Temperature: 226°C (438°F) max for 1 minute dwell time. Temperature measured at a relay ball termination.
