Co LtdThe JK-SMD1210-075 PTC Resettable Fuses with 1210 RoHS from Jinrui Electronic Materials Co Ltd is an over-current or over-temperature protection product that uses positive temperature coefficient (PTC) technology. This component is a thermally-activated resettable fuse that operates by increasing resistance when the current or temperature exceeds the rated values. It has a low-resistance on-state, which is suitable for circuit protection. It features a compact SMD (Surface Mount Device) package and a wide temperature range of -20°C to +85°C. It is also RoHS compliant, meaning it is free of hazardous materials, such as lead and plasticizers, making it safe for environment.
