Why you need these fuses Provide fast overcurrent protection: each fuse quickly opens the circuit when current exceeds the rated value, helping prevent damage to components and wiring. Flexible selection for many jobs: a wide range of current ratings lets you pick the correct protection for sensitive electronics or higher-current circuits. Standard, compact format: 5 x 20 mm ceramic construction fits common 5x20mm fuse clips and holders. Key features and attributes Quantity: 100 pieces per pack. Type: fast ceramic fuses (fast-acting). Size: 5 x 20 mm. Voltage rating: 250 V. Available current ratings: 0.1A, 0.2A, 0.3A, 0.5A, 1A, 2A, 2.5A, 3A, 3.15A, 4A, 5A, 6A, 7A, 8A, 10A, 12A, 15A, 20A, 25A. Function: designed to interrupt the circuit quickly when excessive current flows to protect electrical devices from overcurrent. How this product solves problems Prevents component failure and fire risk by interrupting fault currents before damage spreads. Simplifies inventory and repairs by supplying a broad set of commonly used current ratings in one pack. Makes it easy to match fuse rating to circuit requirements for reliable protection. Typical applications (practical use scenarios) Power supplies and AC/DC adapters: protect downstream circuitry from short circuits and overloads. Consumer and audio electronics: safeguard amplifiers, receivers, and hobby electronics during faults or accidental shorts. LED drivers, chargers, and small appliances: give quick, replaceable protection in compact fuse holders. Quick selection tips Choose the fuse current rating slightly above the normal operating current of the circuit to avoid nuisance blowing while still providing protection. The 5 x 20 mm format is compatible with standard 5x20 fuse holders; confirm holder type before installation. Replace blown fuses only with the same type, voltage rating (250V), size (5x20mm), and appropriate current rating from the list above. Reliability and handling Pack of 100 fuses provides spares for maintenance or multiple projects. Handle and install fuses only when the circuit is de-energized and follow safety precautions for replacement.
