Notch Coil has abundant surface area — much more than a typical spaced coil, which seems to work best in rebuildable sub-ohm tanks. The main “body” of the coil is stainless steel, which heats up quickly and provides super-clean flavor. The leads are non-resistance nickel wire. Notch Coil will work in both, temperature control and power mods.
As for the specs, the Notch Coil has a resistance of 0.23 ohms and an inner diameter of 5.5mm
