Littelfuse Fuses
Littelfuse industrial fuses, power fuses, automotive fuses, axial fuses, cartridge fuses, surface mount fuses, specialty fuses, and medium voltage fuses provide overcurrent protection and regulate current flow in practically every device, machine, and electrical system. When it comes to automotive, industrial, or consumer electronics, Littelfuse fuses might be found providing overcurrent protection in simple or complex circuits. With precise ratings and advanced engineering, they are applied where safety and reliability are paramount.
The Littelfuse fuses part numbering system makes it easy to select the right fuse for just about any application. It is detailed and straightforward enough that we consider it a best practice for our industry to follow when defining and describing our products to ensure user understanding. The parameters it encompasses—like rating, type, and even design—are essential for the accurate identification of not only automotive fuses but also fuse links and medium-voltage fuses. The automotive fuses and links we offer comply with National Automotive Specifications and International standards (ISO), and the medium-voltage fuses are defined by IEC standards. When it comes to overcurrent protection for high-power systems, the specialty fuses and surface-mount options are adequate safeguards against the components they protect—like motors and transformers.
