The square, ceramic surface-mountable SMM series of 3812-size medium-blow fuses have rated current values of 20, 25, and 30 A, and voltage ratings to 250 Vac and 65 Vdc. They are RoHs-compliant, Pb-free halogen free, and resistance to chemical solvents and aqueous cleaning.
The fuses suit overcurrent protection for high-current circuits of large power supplies, as well as in the protection of telecom backplane structures from overloads or short circuits. Additionally, the fuse can isolate a specific section or circuit, allowing the remaining circuits to function normally. The operating temperature ranges from –55° to 85°C with proper derating. (From $0.25 to $0.40 each — available now.)
