  • Publication number: 20240177893
    Abstract: An over-current protection device includes a heat-sensitive layer and an electrode layer. The electrode layer includes a top metal layer and a bottom metal layer, and the heat-sensitive layer attached therebetween. The heat-sensitive layer exhibits a positive temperature coefficient (PTC) characteristic and includes a polymer matrix and a conductive filler. The polymer matrix includes a polyolefin-based homopolymer and a polyolefin-based copolymer. The polyolefin-based homopolymer has a first coefficient of thermal expansion (CTE), and the polyolefin-based copolymer has a second CTE lower than the first CTE. The polyolefin-based homopolymer and the polyolefin-based copolymer together form an interpenetrating polymer network (IPN).
