Computers and other electronic devices contain gold and other precious metals in their circuit boards As consumers upgrade their electronic gadgets the precious metals remain trapped in piles of waste There's about 0 2 grams (0 007 ounces) of gold in a typical mobile phone handset Recovery of

Selective coordination is the selection and application of circuit protective devices in series such that under overload or fault current conditions only the device just up stream from the overload or fault will open to clear the fault The remainder of the circuit's protective devices will remain closed passing power to their individual loads Selectivity can be based upon time or current

Circuit protection is installing a weak link in an electrical circuit intentionally in order to prevent excessive amounts of current or a short circuit To ensure utmost safety Future Electronics offers you a complete range of circuit protection devices like circuit breakers electronic fuses ESD protection diode arrays thyristors gas discharge tubes and more
