See details above. In the reflow soldering process, the fuse must have gold-plated caps, otherwise fuse and clip would be soldered together. For fuse replacement in the field, a standard UMF 250 fuse with tin-plated caps can be used. 2 Fuses UMK 250 Non resettable fuses www.schurter.com/PG01_2 Rated Current [A] Rated Voltage [VAC] Rated Voltage [VDC] Breaking Capacity Voltage Drop 1.0 In max.
