443 250V Nano²® Fuses

Littelfuse 443 250V Nano²^® Fuses are time-lag, surface-mount devices designed to support higher voltage applications that have limited space. These fuses enable compliance with the RoHS directive. They are fully compatible with lead-free solder alloy and higher temperature profiles associated with lead-free assembly. Littelfuse 250V Nano² Fuses are available in ratings of 0.50A to 5.0A. The 443 series is ideal for use in a variety of applications, including AC/DC power adapters, telecom equipment system power applications, portable system built-in AC/DC converters, high voltage DC/DC converters, and lighting systems.
