Subject: S505 Product Change Notification
To continuously improve our products and processes, Cooper Bussmann has made some
modifications to select ratings within the S505 fuse line.
Over the next couple of months there will be a transition to the new design. There will be no
changes to voltage ratings, interrupting ratings or max/min opening times. Changes in time-
current characteristics are minimal. A new datasheet reflecting these changes is now
available online at www.cooperbussmann.com/datasheets/elx.
New material declaration and engineering documents are available upon request.
Fuse dimensions remain the same for all part numbers without axial leads. For fuses with
axial leads (part numbers containing “-V”), some ratings will be fitted with larger diameter
leads. Lead diameter for S505-V-4-R (all prefixes), and S505-V-5-R (all prefixes) has
increased from 0.65mm to 0.81mm.
Thank you for your business and your cooperation with this transition.
