The Rubicon Space Systems 5N Low Throughput (LT) Thruster is designed for small satellite applications.

Its design enables cheaper and faster manufacturability whilst still maintaining high performance, only sacrificing on total throughput. This low-throughput thruster design targets small satellite mission applications where their primary function would be orbit insertions, breaking maneuvers, and de-orbiting.

Rubicon Space Systems, through a NASA STTR Phase I/II, designed, built, and delivered multiple 5N ASCENT thrusters qualified for 3kg of throughput. It was designed for cost-constrained programs with limited propellant throughput requirements. The 5N LT thruster achieved a specific impulse of >260s and an accumulated firing time of almost 25 minutes.
