Sanyou Electrical Appliances, Inc. Automotive Relay SARL-109DD

The SARL-Series is a family of automotive relays designed for high-power switching applications such as fuel pump control, cooling fan control, and rear window defoggers. It features a 40A switching capability at 14VDC, with contact configurations of 1 Form C or 2 Form A, and operates across a temperature range of -40°C to +125°C. The relay uses silver alloy contacts with an initial contact resistance of 100mΩ maximum, and has an operate time of 10ms max and release time of 5ms or 15ms depending on coil circuit type. It meets dielectric strength standards of AC 500V between contacts and coil for 1 minute. The typical unit weight is 32.5g. All variants use the same base design, with differences in coil power, contact material, and accessories such as resistors or diodes indicated by suffixes.
