Product Description
Product Overview
The P-TCO-N Series is a compact, space-saving, polymeric thermal cutoff device designed for thermal protection. Featuring a low-profile and symmetrical 1206 footprint, its small size enables a fast response time to thermal runaway events. This series offers ultra-low resistance and is RoHS compliant and Halogen Free. Key applications include thermal protection for USB-C 2.0, 3.0, and 3.1 cables and ports, as well as mobile device fast charging port protection.
