POLY-FUSE® 1206L series, Polymeric PTC Resettable Fuse, 1206L016WR, 160 mA hold, 370 mA trip, 30 V max, 100 A max, 300 ms trip time, 1206 SMD package.","salesMarkdown":"## Polymeric PTC in a 1206 footprint The Littelfuse 1206L016WR is a surface-mount polymeric PTC resettable fuse from the POLY-FUSE 1206L series, designed for overcurrent protection in compact PCB assemblies. It holds 160 mA continuously at 30 V max and trips at 370 mA, with a maximum interrupt rating of 100 A — enough to clear a hard short on a low-voltage rail without rupturing the package. ## Hold current, trip time, and resistance budget Initial cold resistance is 1.2 Ohms minimum, rising to 4.5 Ohms maximum after a trip event — the post-trip resistance is the figure to budget for voltage drop in the reset state. Typical time to trip at 25 °C is 300 ms at the trip current; a sustained overload above 370 mA will clear within that window, but a fast transient below the trip threshold will not cause a nuisance trip. ## Approvals and sourcing posture The 1206L016WR carries cURus and TUV agency approvals, confirming compliance with North American and European safety standards for polymeric PTC devices.","metaTitle":"Littelfuse 1206L016WR PTC Resettable Fuse, 160 mA Hold, 30V","metaDescription":"Littelfuse 1206L016WR POLY-FUSE polymeric PTC resettable fuse, 160 mA hold current, 30V max, 1206 SMD package.
