Bussmann MDL-1/4-R is a small-dimension time-delay glass fuse rated for 250 V and 0.25 A, sized at 1/4 in by 1-1/4 in (about 6.4 mm x 32 mm) with nickel-plated brass end caps. Time-delay (slow-blow) construction enables it to tolerate brief inrush and inductive loads while still protecting the circuit from overcurrent, making it well suited for compact power supplies, control electronics, and other space-constrained applications where surge handling is important. The fuse is RoHS compliant, and is commonly referenced under alternate catalog numbers such as BK/MDL-1/4 and MDL-1/4-R across distributors, with a 250 VAC rating that supports typical domestic and industrial electronics environments.
