Bel Fuse's 0678H series, 500 mA through 40 A, offers high-amp circuit protection and a compact (9.8 mm x 3.05 mm x 3.05 mm) surface mount form factor to save board space. In addition, the 0678H series enables blade servers to operate at higher power (125 V_DC rating) and includes high melting I²t, which prevents nuisance tripping caused by transient surge during blade server hot swapping.
