Stackpole's RPC Series of surface
mount chips have pulse withstanding in a 5 percent tolerance part. The 5
percent tolerance RPC is completely untrimmed, which allows the entire width of
the resistance element to dissipate the pulse power without any current
crowding. The RPC Series surge withstands thick film chip resistors and are for
applications requiring low cost high pulse handling capability including low to
medium power supplies, broadband and wireless electronics, power control and
motion control systems, medical applications and imaging systems, GPS systems,
ac and dc power modules and backplanes, thermostats, HVAC control systems and
industrial motor controls.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
