SinglFuse™ Part Numbering System

Bourns SinglFuse™ SMD Fuse part numbering system is simple and straight-forward, allowing customers to easily understand key aspects of a SinglFuse product simply by looking at the part number. All models begin with SF, signifying “SinglFuse”. The following 4 numbers represent the product size. In this example here, 2410 represents the fuses 2410 (EIA) size. The following one or two characters denote the fusing speed category. In this case, FP represents Fast Acting Precision. After that, an optional A will indicate AEC-Q200 compliance if the product has been tested and confirmed to meet Bourns’ internal AEC-Q200 equivalency test plan.
