NANO 2 Fuse Simplifying the Fuse Selection Process Fuses are current-sensitive devices that provide reliable protection for discrete components or circuits by melting under current overload conditions. Littelfuse offers a comprehensive range of innovative fuses designed to address an expanding array of circuit protection challenges. However, even seasoned electronics design engineers can discover that identifying the optimum fuse for a specific application can be a confusing, time-consuming process. This Fuse Selection Guide is designed to speed and simplify this process, making it easier to optimize the reliability and performance of the application. The included Fuse Accessories Selection Guide also identifies the fuseholders designed for use with each fuse series.
