Ceramic Fuse > 501 Series 

~~**RoHS Pb** [[_IQHF] Aus @:~~ 

## **Surface Mount Fuses** 

## 501 Series – High Current 1206 Fast-Ac ~~ting Fuse~~ 

## ~~**Description**~~ 

The 501 Series is a 100% Lead-free, RoHS compliant and Halogen-free fuse series designed specifically to provide over- current protection to circuits that operate under high working ambient temperature up to 150°C. 

The general design ensures excellent temperature stability and performance reliability. 

The high I[2] t values which is typical in the Littelfuse Ceramic Fuse family, ensure high inrush current withstand capability. 

## ~~**Features**~~ 

- Operating Temperature • 100% Lead-free, RoHS from -55ºC to +150ºC compliant and Halogenfree 

- Designed to provide over-current protection • Suitable for both leaded in high current voltage and lead-free reflow / regulator module (VRM) wave soldering applications

Notes: 

1. DC Interrupting Rating tested at rated voltage with time constant < 0.5 msec. 

2. Nominal Resistance measured with < 10% rated current. 

Devices designed to carry rated current for 4 hours minimum. It is recommended that devices be operated continuously at no more than 80% rated current. See “Temperature Re-rating Curve”for additional re-rating information. 

3. Nominal Melting I[2] t measured at 1 msec. opening time. For other I[2] t data refer to chart. 

4. Nominal Voltage Drop measured at rated current after temperature has stabilized and with fuse mounted on board with 3-oz Cu trace. 

Devices designed to be mounted with marking code facing up.

Note: 

1. Re-rating depicted in this curve is in addition to the standard re-rating of 20% for continuous operation. 

Example: 

For continuous operation at 75 degrees celsius, the fuse should be rerated as follows: 

- I = (0.80)(0.85)IRAT = (0.68)IRAT
