Determination of suitability for a specific application is the responsibility of the customer. PTCs are typically used as circuit protection in applications where sensitive components are at constant risk of damage from overcurrent conditions. The ability of PTCs to reset themselves after exposure to a fault current makes them ideal within circuits that are not easily accessible to a user or technician or where constant uptime is required. Typical applications include port protection on personal computers (USB, memory card reader, keyboard/mouse and video ports), peripherals (hard drives, video cards, and hubs), cell phone, battery packs, industrial controls, lighting ballast and motor controls. The chart below is meant as a quick guide in narrowing to a Littelfuse PTC device that may be appropriate to certain end applications.
