Overview
The Littelfuse 0805L075SLYR is a surface-mount polymer PTC resettable fuse from the LoRho series, designed for overcurrent protection in compact electronic circuits. It features a 0603 footprint with dimensions of 1.8 mm length, 1.0 mm width, and 0.75 mm height. The device maintains a holding current of 0.75 A and trips at 1.5 A under a maximum voltage rating of 6 VDC. Its initial resistance is typically 165 mOhms, supporting a maximum fault current of 50 A. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Utilizes low-resistance polymer technology to minimize power loss during normal operation
- Provides automatic circuit recovery after fault conditions without manual replacement
- Offers reliable overcurrent protection in a compact surface-mount package
Applications
- Portable consumer electronics battery protection
- USB port overcurrent protection
- Compact automotive electronic modules
Procurement Notes
Verify the specific suffix 'SLYR' against official Littelfuse documentation to confirm tape-and-reel packaging and material composition. Ensure the selected variant matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a 0603 footprint but higher current handling than standard variants allows. The 6 VDC rating suits low-voltage logic and data lines. Compare the 0.75 A holding current against peak operational loads to ensure no nuisance tripping occurs during startup surges. Verify that the 165 mOhms resistance aligns with system power budget requirements.
Part Context
This part belongs to the Littelfuse POLYFUSE LoRho series, which specializes in low-resistance SMD PPTCs. The 0805L prefix indicates the series family, while the numeric code specifies the current rating. The 'SLYR' suffix denotes specific packaging and material attributes defined by the manufacturer for surface-mount integration.
Replacement Considerations
Direct substitutes within the same series include 0605L075SLYR if footprint compatibility allows, or other 0603 L-series parts with matching 0.75 A holding current and 6 VDC rating. Verify that alternative components maintain similar trip currents and resistance values to ensure circuit performance parity.
