Overview
The Littelfuse S8025L52 is a subminiature fast-acting fuse from the 808 Series, rated at 250VAC and 450VDC. It features a TE5 body style with dimensions of 1.6mm x 5.0mm. The device provides an interrupting rating of up to 10kA at 450VDC, ensuring safe operation under high fault currents. Designed for high-voltage DC applications such as power supplies, it operates within a temperature range of -65°C to 125°C. The component is 100% RoHS compliant, halogen-free, and lead-free, offering a compact solution for overcurrent protection in space-constrained designs.
Feature Summary
- High voltage and interrupt rating in a very compact size
- High operating temperature range from -65°C to 125°C
- 100% RoHS compliant, halogen-free and lead-free
Applications
- DC power supplies
- High voltage DC circuit protection
- Energy-efficient DC designs
Procurement Notes
Verify the specific part number against official Littelfuse documentation to confirm the current status and exact electrical ratings. Ensure that the TE5 package dimensions and mounting requirements align with the target PCB layout. Confirm compliance with relevant safety agency approvals required for the end application before finalizing procurement.
Selection Notes
Select this component when space constraints require a subminiature form factor alongside high DC voltage interruption capabilities. The 808 series offers a low-profile alternative to standard cartridge fuses. Consider the 450VDC rating and 10kA interrupting capacity for circuits requiring robust fault protection in high-energy environments.
Part Context
This part belongs to the Littelfuse 808 Series of TE5 subminiature fuses. The series is designed to complement existing DC-rated cartridge fuse offerings, providing circuit designers with greater freedom to develop energy-efficient DC designs. The 808 series emphasizes high performance in a small footprint, suitable for modern electronic equipment where board space is limited.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic substitutes may not match the specific 10kA@450VDC interrupting rating or TE5 dimensional tolerances. Verify that any replacement maintains the same fast-acting characteristic and voltage ratings to ensure circuit safety.
