The AZ9741-1C-12DE is a single-pole double-throw (SPDT) mini-ISO automotive relay designed for PCB mounting. It operates with a nominal coil voltage of 12VDC, has a coil resistance of 90 ohms, and is guaranteed to operate at 7.8VDC. This relay features silver tin oxide contacts and can switch currents up to 40A on its normally open contact and 30A on its normally closed contact. With a wide operating temperature range of -55°C to 125°C and an epoxy-sealed enclosure, it is well-suited for high-stress automotive environments and other applications requiring reliable high-current switching.
