Rutronik Adds Omron G9JH-1-E DC Relay for Inrush Protection
Weighing just 36 g, the smallest DC relay in the industry, Omron’s G9JH-1-E, available via Rutronik, withstands 100,000+ switches, 30 A inrush, -40 °C to +85 °C, and 4,500 V impulse.

New in Rutronik's portfolio is the G9JH-1-E DC relay from Omron. Currently the smallest relay in the industry, weighing only 36 g, this 800 VDC relay has been specifically designed for pre-charge applications and is used, among other things, as an inrush current limiter for main relays. The relay withstands at least 100,000 switching operations under a capacitive load of 800 VDC with inrush currents up to 30 A and is specified for operating temperatures from -40 °C to +85 °C. Thanks to its low contact resistance of maximum 100 mΩ, the robust component features very low power dissipation. It also provides shock resistance up to 490 m/s² and impulse withstand voltage up to 4,500 V. It's ideally suited for applications in energy storage or electric vehicle charging systems.
Both the operating and release times of the relay are just 30 ms. The high dielectric strength (2,500 VAC/min between contacts of the same polarity, as well as between coil and contact) and the high insulation resistance (1,000 mΩ between coil and contact as well as between contacts of the same polarity) further increase both efficiency and durability. At 15 A, the contact voltage drop is only 0.2 V (maximum).
