Introduction
Resettable PPTC (Polymeric Positive Temperature Coefficient) fuses are essential components for overcurrent protection in various electronic circuits. These fuses utilize a polymeric material embedded with conductive particles that change resistance under overcurrent and thermal stress, providing automatic reset functionality once normal conditions return. This makes them highly desirable in electronics requiring low maintenance and durable protection.

Market Overview
global Resettable PPTC Fuse market was valued at USD 284.28 million in 2023 and is expected to reach USD 319.89 million by 2030, growing at a CAGR of 2.72% from 2024 to 2030. The demand is driven by growth in electronics, telecom, and automotive sectors, as well as increasing adoption of compact smart devices and stringent safety requirements.
