Add to your addressable led kit between your controller and led strips/halos/chains. Used to prevent voltage spikes on the 12+/- line with a capacitor, and also on your data lines with an inline resistor.

Installation: Apply dielectric grease to pins and plug into your controller outputs. Seal with heat shrink. 10 seconds of work.

The component is potted & waterproof, however, as with all JST connections, we highly suggest dielectric grease and heat-shrink on all connections.
