Durakool’s PCB automotive relays offer high continuous and inrush current capability, compact, sealed or open variants. They provide low coil power consumption, stable operate and release voltages, low contact resistance, strong dielectric and insulation performance for reliable DC switching. Thermal efficient designs and PCB-friendly pin layouts make heat management and integration easier in space-limited control modules. Standardised form factors reduce redesign work, while durable contact materials and long electrical and mechanical life help reduce testing and lifecycle risks. Customisation is available to match specific current, voltage, coil, or environmental needs, giving engineers greater flexibility in design.
Want guidance on choosing the right automotive PCB relay? We’re here to help.
