Overview
The Littelfuse 0603L001/60YR is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in compact electronic circuits. It operates with a maximum voltage rating of 60 VDC and maintains a hold current of 100 mA. The device trips at 300 mA and withstands a maximum trip current of 40 A. Featuring a 0603 package, it offers low resistance and reliable performance across a temperature range of -40°C to +85°C.
Feature Summary
- Provides automatic circuit reset capability after fault conditions clear
- Designed for high-reliability surface-mount integration
- Offers dual electrical and thermal protection mechanisms
Applications
- Portable consumer electronics battery protection
- USB peripheral interface overcurrent safeguarding
- Automotive infotainment system circuit protection
Procurement Notes
Verify the specific suffix YR against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required operating temperature range and voltage derating curves for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require resettable protection for low-current DC lines. Evaluate the trip current threshold relative to the normal operating current to prevent nuisance tripping during startup surges. Confirm compatibility with standard reflow soldering profiles used in the manufacturing assembly process.
Part Context
This part belongs to the 0603L series of miniature PPTC devices from Littelfuse. These components are engineered specifically for applications where traditional fuses are impractical due to size constraints or the need for maintenance-free operation. The series supports various voltage and current ratings within the standard 0603 footprint.
Replacement Considerations
Consult Littelfuse datasheets for direct cross-reference models within the 0603L family that match the 60VDC and 100mA specifications. Verify that any substitute maintains identical package dimensions and thermal characteristics to ensure mechanical fit.
