•
RoHS compliant and Lead-Free.
• For new designs of 7 amp please consult 429 series.
• Product is compatible with lead-free solders and higher
temperature profiles.
• Current ratings available up to 5A.
• High performance materials provide improved performance in elevated
ambient temperature applications.
• Product is marked on top surface with code to allow amperage rating
identification without testing.
• Low profile for height sensitive applications.
• Flat top surface for pick-and-place operations.
• Element covering material is resistant to industry standard
cleaning operations.
• Mounting pad and electrical performance is identical to Littelfuse 429
and 433 Series products.
• Alloy based element construction provides superior inrush withstand
characteristics (I
2
t) over ceramic or glass based 1206 chip fuse products.
