Medium-blow fuses suit high-current apps

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.)

Bel and its groups are primarily engaged in the design, manufacture, and sale of products used in networking, telecommunications, high-speed data transmission, commercial aerospace, military, transportation, and consumer electronics.
