Coto’s Ball Grid Array (BGA) construction offers a break- through in reed relay performance. This patented technology 1 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-in- one BGA packaging allows relays to be integrated easily on boards designed for surface mount processing. Notes:

Contact resistance >2.0 Ω defines end of life. 4Frequency at which the difference between output and input signal amplitude exceeds -3dB. 5Maximum 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 T emperature: -35°C to +100°C. Operating T emperature: -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 nomi- nal coil voltage to open, nor an open channel to close. Max Soldering T emperature: 438°F(226°C) for 1 minute dwell time. T emperature measured at a relay ball termination. Moisture sensitive component. Handle as J-STD-020B level 5a.
