Multi-layer Slow Blow Fuses Help Protect Automotive Infotainment
|
From Tyco Electronics, Raychem Circuit Protection Products
Automotive infotainment designs must provide adequate power protection over an increasingly broad range of voltages, currents and temperatures. While the manufacturer's primary design goal may be to improve and expand product functionality, a good design will also focus on product survivability across all definable environments. Many devices, once exposed to repeated overtemperature conditions, may no longer perform to specification and may begin to draw higher and higher currents in order to maintain functionality. With enough of these degraded components incorporated into a system design, the inrush currents may begin to exceed even the most conservative design criteria. Selecting a fuse with slow blow characteristics, high current carrying capability, and high pulse withstand is critical in such designs. Read the rest of the story... Products & Services
Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.
