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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
