## **501A Series** High Current 1206 Fast-Acting Fuse 

## **RoHS Pb** [JQHF Adis G. 

## **Description** 

The 501A series AECQ-Compliant fuses and Halogen free fuse series are specifically tested to cater to secondary circuit protection needs of compact auto electronics application. The general design ensures excellent temperature stability and performance reliability. The high I2t values which are typical in the Littelfuse Ceramic Fuse family, ensure high inrush current withstanding capability. 

## **Features & Benefits** 

- Operating Temperature from ■ Suitable for both leaded and -55ºC to +150ºC lead-free reflow/wave soldering 

## **Additional Information** 

- Meets Littelfuse’s ■ Recognized to UL/CSA/NMX automotive qualifications* 248-1 and UL/CSA/NMX 24814 

- 100% Lead-free, RoHS compliant and Halogen-free 

- Largely based on Littelfuse internal AEC-Q200 test plan

## **Notes:** 

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

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

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

Devices designed to carry rated current for four 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. 

Devices designed to be mounted with marking code facing up. 

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

## **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)IN = (0.68)IN
