Overview
The Littelfuse 0603L075SLYR is a surface-mount polymer PTC resettable fuse from the LoRho series, designed for circuit overcurrent protection. It features a 0603 (1608 metric) package with dimensions of 1.8 mm length, 1 mm width, and 0.75 mm height. The device has a maximum voltage rating of 6 VDC and a trip current of 1.5 A. Its hold current is specified at 750 mA, with a maximum fault current rating of 50 A. The initial resistance is 165 mOhms, and power dissipation is rated at 600 mW. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Utilizes polymer positive temperature coefficient technology for automatic reset functionality after fault conditions clear.
- Features low resistance characteristics inherent to the LoRho series design for minimal signal impact.
- Complies with RoHS 3 standards and is halogen-free for environmentally compliant manufacturing.
Applications
- Portable electronic devices requiring compact overcurrent protection
- Consumer electronics circuits with limited space constraints
- Data port protection in mobile communication hardware
Procurement Notes
Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm that the received parts match the specific 0603L075SLYR designation and packaging format. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain solderability and performance integrity prior to assembly.
Selection Notes
Select this component when circuit protection is required within a 6 VDC system limit. The 750 mA hold current suits applications where normal operating current remains below this threshold. Consider the 0603 footprint compatibility with existing PCB layouts. Evaluate thermal management needs as power dissipation affects tripping behavior in enclosed environments.
Part Context
This part belongs to the POLY-FUSE LoRho series, which focuses on low-resistance surface-mount solutions. The series provides alternatives to traditional fuses by offering reusable protection mechanisms. The 0603 size allows for high-density mounting on printed circuit boards, supporting modern miniaturization trends in electronic product design.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 0603L series variants only if electrical parameters such as hold current and voltage ratings align precisely with system requirements.
