1812L035/30DR Description

Short technical summary and product information.

The Littelfuse 1812L035/30DR is a polymeric PTC resettable fuse from the 1812L series, designed for surface mount overcurrent protection. It provides resettable protection in applications where traditional fuses would need replacement. The device is RoHS compliant, lead-free, and halogen-free, making it suitable for environmentally conscious designs.

 

Key electrical specifications include a hold current of 0.35A, trip current of 0.75A, maximum voltage of 30V DC, and maximum interrupt current of 40A. Typical power dissipation is 0.8W. The resistance ranges from 0.4Ω (minimum) to 1.7Ω (maximum after trip). The time to trip at 8A is typically 150 ms. The operating temperature range is -40°C to 85°C.

 

The device is packaged in a 1812 (4532 Metric) concave surface mount package, with dimensions approximately 4.55mm x 3.24mm x 1.25mm. It is compatible with high temperature soldering processes. The 1812L series is recognized by UL (file E183209) and TUV (file R50119118) for safety.

 

Typical applications include plug and play protection for motherboards and peripherals, USB peripherals, PCI cards, and game console port protection. The compact design and low resistance make it ideal for space-constrained designs requiring resettable overcurrent protection.
