The Littelfuse 466 Series Fast-Acting Surface Mount Fuse (SMF) is a compact, thin-film device specifically engineered for secondary circuit protection in applications where space is limited, such as hand-held portable electronic devices. This series is 100% lead-free and meets RoHS requirements, with halogen-free options available. The fuse features an alloy-based element top surface marked with a code for amperage identification and a conformal coating for resistance to cleaning profiles. Its low profile and flat top surface are optimized for pick-and-place operations, making it suitable for automated assembly processes. Common applications include cell phones, DVD players, battery packs, hard disk drives, and digital cameras.
