Surface Mount Fuses

Thin-Film Surface Mount

1206 Slo-Blo^®Fuse 430 Series

• For RoHS compliant and Lead-Free designs use 468 series

• Time delay feature withstands high in-rush currents and prevents

nuisance openings.

• Package is visually distinct from fast-acting version for easy identification.

• Top side marking allows visual verification of amperage rating.
