0603L100SLYR Description

Short technical summary and product information.

The 0603L100SLYR is a polymeric PTC resettable fuse from Littelfuse, designed for overcurrent protection in low-voltage electronic circuits. It features a hold current of 1A and a trip current of 2.7A (from similar part datasheet, not confirmed for this specific part).

 

The device has a voltage rating of 6V and a maximum voltage of 16V (from VTP110F datasheet, unconfirmed). The time to trip is 300ms, and the maximum initial resistance is 120mΩ, ensuring low power dissipation during normal operation.

 

This fuse is surface mountable in a compact 0603 (1608 Metric) concave package, with dimensions 1.60mm x 0.80mm x 0.75mm. It is suitable for high-volume automated assembly and is compatible with standard reflow soldering processes.

 

The operating temperature range is -40°C to 85°C, making it suitable for a wide range of environments. Compliance with RoHS3 and REACH is claimed but unverified.
