Overview
The Littelfuse 0805L010YR is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the 0805L series. It features a maximum voltage rating of 15 VDC and a hold current of 0.1 A. The device trips at a current of 0.3 A within 1.5 seconds. Its initial resistance ranges from a minimum of 1 Ω to a maximum of 6 Ω, with a power dissipation capability of 0.5 W. The component operates within a temperature range of -40°C to +85°C and utilizes tin-plated copper terminals in an 0805 package.
Feature Summary
- Provides automatic circuit protection through self-resetting PTC technology
- Designed for surface-mount installation on printed circuit boards
- Offers overcurrent protection against excessive heat generation
Applications
- Portable electronic devices requiring compact circuit protection
- Consumer electronics circuits needing low-voltage safeguarding
- Communication equipment interfaces
Procurement Notes
Verify the specific manufacturer part number 0805L010YR against official Littelfuse documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with surface-mount assembly processes and operating temperature requirements. Confirm RoHS compliance status through certified datasheets prior to integration into final designs.
Selection Notes
Select this component when designing circuits requiring a 15 VDC maximum voltage rating and a 0.1 A hold current. Consider the 0.3 A trip threshold and 1.5-second response time for appropriate fault protection coordination. Evaluate the 1 Ω to 6 Ω resistance range for impact on signal integrity or power loss in sensitive applications.
Part Context
This device belongs to the Littelfuse 0805L series of polymer PTC resettable fuses. These components are engineered for surface-mount technology applications where space constraints are critical. The series provides reliable overcurrent protection for various electronic systems without requiring manual replacement after fault clearance.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalent part numbers. Do not assume cross-compatibility with other manufacturers' 0805 PTC devices due to potential differences in trip characteristics and thermal performance.
