Circuit protection has become a crucial design consideration to protect applications against overcurrent conditions. These conditions can lead to costly field failures so ignoring circuit protection is not an option. Resettable fuses are an attractive solution and have been widely adopted in a variety of applications. This white paper details some of the latest circuit protection advancements, and demonstrates how Bourns’ line of resettable Multifuse® products can enable cost-effective and reliable protection that matches design objectives while eliminating design constraints.
