The Littelfuse 1812L110/33MR is a surface mount polymeric PTC resettable fuse from the 1812L series, designed for overcurrent protection in a wide range of electronic applications. It offers a hold current of 1.1 A and a trip current of 1.95 A, with a maximum voltage rating of 33 V and a maximum interrupt current of 20 A. The device has a typical power dissipation of 0.8 W and a fast time-to-trip of 500 ms at 8 A.
This PTC fuse features low resistance values, with an initial minimum resistance of 60 mΩ and a maximum post-trip resistance of 200 mΩ, ensuring minimal power loss during normal operation. It is housed in a standard 1812 (4532 Metric) concave package, suitable for automated surface mount assembly. The component is RoHS compliant, lead-free, and halogen-free, meeting modern environmental standards.
Typical applications include plug-and-play protection for motherboards and peripherals, USB port protection, PCI cards, and game console port protection. The device operates over a temperature range of -40°C to 85°C, making it suitable for both consumer and industrial environments.
