NASA’s Perseverance Rover recently made a successful landing on Mars, embarking on a two-year mission to seek signs of ancient life and collect samples. Because Mars is extremely cold—nighttime temperatures can drop below -112 F—heaters are required to keep the rover’s battery system from freezing. Now, researchers reporting in ACS’ Nano Letters have 3D printed porous carbon aerogels for electrodes in ultralow-temperature supercapacitors, reducing heating needs for future space and polar missions.

These chokes are available in three sizes with current handling capacities between 10 A and 17 A, and with a rated voltage of 250 V AC (50/60 Hz). Depending on the type, the inductance value is between 1.0 mH and 6.25 mH. The plastic material of the base plate and spacer in the middle of the ring core conforms with UL 94 V-0, and the highest CTI value of >600.
