The AZ977-1A-12D is a 20 Amp micro-ISO automotive relay featuring a 12 VDC coil with Form A (SPST) contact arrangement, designed for high in-rush applications in compact automotive environments. The relay delivers up to 20 Amp switching capability with a maximum switched power of 280 W and maximum switched voltage of 150 VDC, while maintaining a contact resistance of less than 50 milliohms. It operates over an ambient temperature range of -40°C to 115°C with mechanical life expectancy of 1×106 operations and electrical life of 1×105 operations at 20 A and 14 VDC. The relay features silver tin oxide contacts, vibration and shock resistance (0.062" DA at 10-55 Hz and 10 g shock), and meets ISO/TS 16949 and ISO14001 standards. Its compact footprint, quick-connect terminals, and cost-effective design make it ideal for automotive switching applications requiring reliable high-current performance.
