DESCRIPTION

3SBC1785A2 is a double-pole, electrically held low-signal relay designed for aerospace, defense, and marine applications. This 0.150-inch grid-space relay features a compact profile of only 0.32 inches in height, enabling space-efficient integration into electronic packaging. The relay is qualified to MIL-R-39016/13 and offers contact ratings of 2 amps at 28 volts DC for resistive loads (50,000 operations) and 1 amp at 28 volts for 100,000 operations, with low-level switching capability of 50 µA at 50 mV. Operating characteristics include a maximum operate time of 4 ms, release time of 4 ms, and contact bounce of 1.5 ms, with contact resistance of 0.050 ohms maximum and 0.150 ohms after life testing. The relay operates reliably across a temperature range of -65°C to +125°C and withstands vibration up to 30G to 3000 Hz and shock of 100G at 11 ms, making it suitable for demanding military and aerospace switching applications requiring high reliability and compact form factors.
