Keystone Electronics’ 3557-2 fuse holder minimizes the need for design engineers to design and test multiple fuse holders to accommodate Littelfuse ATO 257 Series, Bussman ATC Series, Littelfuse low-profile mini 897 series and equivalent style fuses. A standard footprint simplifies the board design process and allows for flexibility in designing for circuit protection. Keystone says the fuse holders reduce the amount of necessary production components and give design engineers the ability to design high- or low-profile fuses at the beginning of their design cycles.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
