Ten 5 x 20 mm fast-blow glass cartridge fuses — 0.1 A, 250 V Key benefits Protects electronics and circuits quickly: fast-acting element clears small overcurrents before they damage sensitive components. Easy inspection and maintenance: clear glass body shows fuse condition at a glance for faster troubleshooting. Simple replacement and inventory control: standard 5 x 20 mm size fits common holders and fuse blocks; sold as a pack of ten for spare parts or multiple devices. What makes these fuses useful Fast blow characteristics provide precise, rapid response to short-duration faults and inrush conditions where quick isolation is needed. Standard form factor and metal end caps ensure reliable contact in standard 5x20 mm fuse holders and blocks. Transparent glass tube lets you confirm blown fuses visually without disassembly. Specifications Quantity: 10 fuses Size: 5 x 20 mm (fits standard 5x20 mm holders and blocks) Voltage rating: 250 V Current rating (this set): 0.1 A (note: these fuses are part of a family that ranges from 0.1 A to 30 A; examples include 0.2 A, 0.5 A, 1 A, 1.5 A, 2 A, 2.5 A, 3 A, 3.15 A, 4 A, 5 A, 6 A, 7 A, 8 A, 10 A, 12 A, 15 A, 20 A, 30 A) Construction: clear glass tube with metal end caps; fast-acting fuse element Typical applications Low-power electronics and hobby projects where precise, quick protection is required (e.g., microcontroller boards, small amplifiers, test fixtures). Power supplies and consumer devices using standard 5x20 mm fuse holders (e.g., bench supplies, chargers, desktop equipment). DIY or small automotive/electrical builds that need rapid fault isolation for sensitive circuits. Usage and safety notes Confirm that a 0.1 A fast-blow fuse is the correct type and rating for your circuit; using an incorrect rating can lead to insufficient protection or nuisance blowing. Designed for overcurrent protection in electrical circuits; install in approved fuse holders and observe proper polarity where applicable. Replace blown fuses only with the same size, voltage, and current rating to maintain safety and performance.
