Fuse **Datasheet** 

**466 Series** 1206 Fast-Acting Fuse 

## **RoHS Pb** ~~C~~ XHAL IOHFWG 

## **Description** 

The 466 Series Fast-Acting 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 466 Series fuses are available to order using the “HF” suffix. See Part Numbering section for additional information. 

## **Features & Benefits** 

- Product is compatible with ■ Lead-free, Halogen-free and lead-free solders and higher RoHS compliant temperature profiles ■ Recognized to UL/CSA/NMX 

- ■ Product is marked on top 248-1 and UL/CSA/NMX 248surface with code to allow 14 amperage rating identification ■ Conforms to EN 60127-1 and without testing EN 60127-7 

## **Additional Information** 

- Low profile for height sensitive applications 

   - CE Mark indicates suitability for the European Market 

- Flat top surface for pick-and■ UKCA Mark indicates place operations suitability for the UK Market 

- Element-covering material is resistant to industry standard cleaning operations

## **Temperature Re-rating Curve** 

**==> picture [243 x 164] intentionally omitted <==**

## **Note:** 

**1.** Re-rating depicted in this curve is in addition to the standard re-rating of 25% for continuous operation. **Example:** 

- For continuous operation at 70 degrees celsius, the fuse should be rerated as 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.
