DURAKOOL DG17M Ultra-Miniature SPST-NO-DM Automotive Relay, 12V DC, 15A

The DURAKOOL DG17M series is an ultra-miniature PCB-mounting relay engineered specifically for demanding pre-charge and discharge applications within the automotive sector. Its compact footprint and robust, sealed IP67 construction make it an ideal solution for vehicle electronics where space is limited and reliability is critical.

Designed with an automotive orientation, this relay features a SPST-NO-DM (Single Pole Single Throw, Normally Open, Dual Make) contact configuration. The contacts are made from durable Silver Tin Oxide (AgSnO2) material, ensuring excellent electrical conductivity and resistance to welding and arc erosion under high load conditions. It is rated for a maximum switching current of 15A and can handle up to 450VDC, making it suitable for controlling various in-vehicle circuits.

Operation is both fast and efficient, with a typical operate time of 3ms and a release time of 1.5ms. The coil is rated for 12VDC nominal voltage, drawing approximately 92mA with a coil resistance of 130 ohm at 30°C. A built-in magnetic arc blowout feature enhances performance and longevity by effectively extinguishing arcs during switching.

The relay's miniature case style facilitates high-density PCB layouts. Its Through Hole (PC Pin) termination ensures a secure and reliable solder connection. The sealed design meets IP67 standards, providing superior protection against dust ingress and temporary immersion in water, which is essential for under-hood or other exposed automotive environments.

With an operational ambient temperature range from -40°C to +85°C, low contact resistance of 10mohm at 20A, and a lightweight construction of just 14 grams, this DURAKOOL relay delivers exceptional performance and durability for advanced automotive electrical systems.
