POLY-FUSE® 1206L series, Type Polymeric, PTC Resettable Fuse, 1206L075THYR, 750 mA hold, 8V max, 100A max, 200 ms trip, Surface Mount 1206 (3216 Metric) Concave.","salesMarkdown":"The 1206L075THYR is a polymeric PTC resettable fuse from the POLY-FUSE® 1206L series, rated to hold 750 mA continuously at up to 8V without tripping. When a fault pushes current above the trip threshold (1.5 A typical), the internal polymer heats and the resistance jumps — the device limits the fault to protect the downstream circuitry. The 100 A maximum fault current rating means it can safely interrupt a dead short on a low-voltage rail without rupturing the package. The concave termination style is common for PTCs — it gives good solder-joint visibility under inspection and the pad layout matches standard 1206 footprints. The initial resistance is 90 mOhms minimum, rising to 290 mOhms maximum after a trip event, which is typical for this class and keeps the voltage drop under 70 mV at rated hold current. ## Active production and sourcing posture Approvals include cURus and TUV, which cover UL 1434 and IEC 60738-1 respectively — the two main standards for polymeric PTC overcurrent protectors.","metaTitle":"Littelfuse 1206L075THYR PTC Resettable Fuse, 750mA Hold, 8V","metaDescription":"Active Littelfuse 1206L075THYR polymeric PTC resettable fuse, 750 mA hold current, 8V max, 100A max fault. cURus, TUV approved.
