Automotive Relays

Automotive relays are core control components in a vehicle's electrical system, fulfilling the critical function of controlling high-current circuits with low current. As the "smart switch" of onboard circuits, their reliability directly impacts the stability of the entire vehicle's electrical system. According to the latest industry standards set for 2025, modern automotive relays must meet AEC-Q100 certification and extend their operating temperature range to -40°C to 125°C.
