3812-size fusesBel Fuse introduced its square ceramic surface-mountable SMM Series of 3812 size medium-blow fuses. SMD fuses with rated current values up to 30 A and with voltage ratings up to 250 VAC and 65 VDC, they address the industry's requirements for devices supporting high power consumption with limited board space. RoHs-compliant, Pb-free and halogen free, these parts additionally feature desirable mechanical integrity, and resistance to chemical solvents and aqueous cleaning. The new SMM fuses are appropriate for overcurrent protection in high-current applications in which a small form factor device is specified to optimize board space. Included among their most common usage is in the protection of high-current circuits (primary or secondary) of larger power supplies, as well as in the protection of (telecom) backplane structures from overloads or short circuits, which could disrupt an entire system. The SMM fuse can isolate a specific section or circuit, allowing the remaining circuits to function normally.
