The LittleFuse Nano2 451 series fuses have been updated to meet RoHS compliance and are now halogen-free, with two new suffix options. The first part of the suffix remains unchanged: ‘MR’ denotes 1000-piece tape and reel, while ‘NR’ indicates 5000-piece tape and reel. Following these two options, there ]are now two additional suffix options to choose from: ‘L’ for gold-plated end caps and ‘SN’ for silver-plated end caps. All part numbers without the ‘L’ or ‘SN’ suffix have been made obsolete and replaced by the new RoHS-compliant and halogen-free versions.
