Overview

Spintronic capacitors store energy. They also double as a spintronic voltmeter: The gauge on top indicates the spin voltage across it from -9 to +9 spin volts.

Detailed description

These spintronic capacitors have a fixed value of 1.2 mF. The capacitors use a torsion spring to store energy and exhibit low hysteresis. These capacitors are rated for a maximum of +/- 9 spin volts.

Joshua ★★★★★ Oct 11, 2026

The built-in voltmeter gauge is incredibly handy—I can read spin voltage at a glance without extra wiring. Charged up smoothly and holds steady in my spintronics rig.

Violet ★★★★★ Sep 15, 2026

I swapped this into my bench rig to smooth out voltage ripple and it holds a steady charge way longer than the old cap I was using. The built-in gauge is the real bonus, letting me eyeball the spin voltage anywhere from -9 to +9 without dragging out the multimeter.

Daniel F. ★★★★★ Sep 14, 2026

Didn't expect the gauge on top to be this handy — I can watch the spin voltage swing from -9 to +9 while it's holding a charge. The 1.2 mF capacity covers my small rigs fine.
