*1: Measured at 10% or less of the rated current.
*2: Joule integral is the value at 1 ms of I²t characteristics.
*3: For leaded item numbers, 1–5 A uses F4.7LM, and 6.3–10 A uses CUF4.7LM.
*4: For non-leaded item numbers, 1–5 A uses LM, and 6.3–10 A uses CULM.
Note: CU indicates copper fuse element, F4.7 indicates the terminal shape, and LM indicates laser marking.
