Features产品特点： ? Compatible with leadfree solders and higher temperature profiles. ? High performance materials provide improved performance in elevated ambient temperature applications. ? Marked on top surface with code to allow amp rating identification without testing. ? Low profile for height sensitive applications. ? Flat top surface for pickand-place operations. ? Element covering material is resistant to industry standard cleaning operations. ? Mounting pad and electrical performance is identical to Littelfuse 431 and 434 Series products. ? Alloy based element construction provides superior inrush withstand characteristics (I2t) over ceramic or glass based 0603 fuse products. Applications产品应用： Secondary protection for space constrained applications: ? Cell phones ? Battery packs ? Digital cameras ? DVD players ? Hard disk drives.
