Available in industry standard 0402, 0603, and 1206 chip sizes, the surface-mount fuse line offers small size, high reliability, strong arc suppression characteristics and the highest current ratings available in both 0402 and 0603 form factors.
The fuse features clear time characteristics of 4h minimum at 100% of rated current, 5s maximum at 250% of rated current, and 0.05s maximum at 400% of rated current.
The fuse's monolithic, multilayer design provides the highest hold current in the smallest footprint, reduces diffusion-related aging, improves product reliability and resilience, and enhances high temperature performance in a wide range of circuit protection designs.
