## **Description**
The 468 Series Slo-Blo® Surface Mount Fuse (SMF) is a small (1206 size) thin-film device designed for secondary protection of circuits used in space constrained applications such as hand-held portable electronic devices.
This series is 100% lead-free and meets the requirements of the RoHS directive. New Halogen-Free 468 Series fuses are available– to order use the “HF” suffix. See Part Numbering section for additional information.
## **Features and Benefits**
- Complies with electronic ■ Package is visually distinct industry environmental from fast-acting version for standards for lead reduction. easy identification.
## **Additional Information**
- Product is compatible with lead-free solders and higher temperature profiles.
- Top side marking allows visual verification of amperage rating.
- Time delay feature ■ Lead-free, halogen-free and withstands high inrush ROHS compliant. currents and prevents nuisance openings.

## **Note:**
**1.** Rerating depicted in this curve is in addition to the standard derating of 25% for continuous operation. **Example:**
- For continuous operation at 70 degrees celsius, the fuse should be deratedas follows: I = (0.75)(0.80)IRAT = (0.60)IRAT
**2.** The temperature derating curve represents the nominal conditions. For questions about temperature derating curve, please consult Littelfuse technical support for assistance.
