Business Wire
Released today by Bel Fuse (NASDAQ: BELFA) (NASDAQ: BELFB), a
premier developer of fuses and magnetic-based solutions for
high-speed networking and computer applications, is the square
ceramic surface-mountable SMM Series of 3812 size medium-blow
fuses. SMD fuses with rated current values up to 30A and with
voltage ratings up to 250VAC and 65VDC, they satisfy the industry's
requirements for devices supporting high power consumption with
limited board space. RoHs-compliant, Pb-free and halogen free,
Bel's environmentally friendly parts additionally feature superior
mechanical integrity, and resistance to chemical solvents and
aqueous cleaning.
The new SMM fuses are ideal for overcurrent protection in a
broad spectrum of 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.
Notably, the SMM fuse can isolate a specific section or circuit,
allowing the remaining circuits to function normally.
Offered with 20A, 25A, and 30A ratings, Bel's SMM Series
features an operating temperature range of -55 degrees C to +85
degrees C with proper derating. At 100% of ampere rating, opening
time is 4 hours minimum; 60 seconds maximum at 200% of ampere
rating. Fuses are manufactured of ceramic bodies with matte tin
plated brass caps. Parts are provided on 13" reels, 2,000 per reel.

In production quantities, per-piece pricing for the square
ceramic surface-mountable SMM Series of 3812 size medium-blow fuses
ranges from $0.25 to $0.40 each. Samples are available from stock.
