Lead-Free 1206

Very Fast Acting Fuse 466 Series

TIME IN SECONDS

NEW

•

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

t) over ceramic or glass based 1206 chip fuse products.
