BK/MDL-1-1/4 is a time-delay glass tube fuse designed for overcurrent protection in electronic and electrical applications. This fuse features a 1/4" diameter x 1-1/4" length form factor and is rated at 1-1/4 amps. The time-delay characteristic allows the fuse to withstand temporary inrush currents while still providing reliable protection against sustained overloads. MDL series fuses are commonly used in appliances and consumer electronics where precise circuit protection is required. The glass tube construction allows for visual inspection of the fuse element status.
