of Coin Cell Style Supercapacitors provide on-board memory backup a longer life
spans than batteries. With 0.15 to 8 Farads of capacity and voltages up to 5.5 WV
dc these devices supply power to prevent loss of data during a power
interruption and are available in three case configurations for horizontal,
vertical and center-lead mounting. The dc Series includes values and lead
combinations with case sizes as small as 6.8 x 4.6 mm. The operating temperature
ranges from -40 to +85C and 90-95 percent relative humidity. Other features include
fast charge/discharge cycling, IEC 62391 and RoHS compliance and low ESR.
capacitors board mount in applications such as smart meters, HVAC
controls, building automation, business phone systems, appliances, instruments
and other microprocessor-based devices. Because of their high power
density, they can help to reduce board size and case requirements.
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.
