SMD Autofuses

SMD autofuses perform the same overcurrent protection functions as automotive blade fuses. The difference for SMD autofuses is their configuration. Compact and optimized to mount on the surface of printed circuit boards, SMD autofuses deliver weight savings without compromising circuit protection.
