The 3SBC1683A2 is a double-pole, double-throw (2PDT) low-signal relay designed for aerospace, defense, and marine applications with a compact 0.150-inch grid-space form factor and low profile of only 0.32 inches high. This hermetically sealed relay features a maximum switching capacity of 2 amps at 28 volts DC (50,000 operations) and 1 amp at 28 volts DC (100,000 operations), with coil resistance of 44 ohms ± 10% at 25°C and a nominal coil voltage of 3.5 to 6.2 volts. The relay exhibits excellent RF switching performance, high shock and vibration ratings up to 30G (55 to 3000 Hz), and operates reliably over a temperature range of -65°C to +125°C with contact resistance of 0.050 ohms maximum and 0.150 ohms after life test. Its low-profile design and pin spacing allow direct insertion without intermediate pin spreaders, making it ideal for space-constrained electronic packaging in military and aerospace systems requiring MIL-R-39016 qualification.
