RoHS compliant and Lead-Free.
鈥?Product is compatible with lead-free solders and higher
temperature profiles.
鈥?High performance materials provide improved performance in elevated
ambient temperature applications.
鈥?Product is marked on top surface with code to allow amperage rating
identification without testing.
鈥?Low profile for height sensitive applications.
鈥?Flat top surface for pick-and-place operations.
鈥?Element covering material is resistant to industry standard
cleaning operations.
鈥?Mounting pad and electrical performance is identical to Littelfuse 431
and 434 Series products.
鈥?Alloy based element construction provides superior inrush withstand
characteristics (I
2
t) over ceramic or glass based 0603 fuse products.
