1206HV-2A
Fast Acting | 0.126x0.064 inch
Thick Film Chip Fuses
1206HV Series are the fuses set the industry standard for performance, reliability and quality. The solder-free design provides excellent on-off and temperature cycling characteristics during use and also makes our SMD fuses more heat and shock tolerant than typical subminiature fuses.
