描述
NANO2慢熔型保险丝耐受突入电流的特性比NANO2快熔型保险丝更优异。该保险丝设计中独特的延时特性有助于解决误“断路”问题，因为可能耐受突入电流，而快熔型保险丝在出现此类电流时往往会熔断。功能与特色:

SURFACE MOUNT FUSES

SUBMINIATURE SURFACE MOUNT

NANO^2®SMF Slo-Blo^®Type Fuse

The very small NANO²Fuse with time delay performance

characteristics. The unique time delay feature of this fuse

design helps solve the problem of nuisance “opening” by

accommodating inrush currents that normally cause a fast-

acting fuse to open.
