Description

The 501A series AEC-Qualified 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. Agency Approvals Agency Agency File Number Ampere Range E10480 10A - 20A 29862 10A - 20A Features & Benefits ■ Operating Temperature from -55ºC to +150ºC ■ 100% Lead-free, RoHS compliant and Halogen-free ■ Suitable for both leaded and lead-free reflow/wave soldering ■ Recognized to UL/CSA/NMX 248-1 and UL/CSA/NMX 248- ■ AEC-Q200 Qualified Electrical Characteristics for Series % of Ampere Rating Ampere Rating Opening Time at 25ºC 100% 10A – 20A 4 Hours, Minimum 350% 10A – 20A 5 Seconds, Maximum

DC Interrupting Rating tested at rated voltage with time constant <0.5msec. 2. Nominal Resistance measured with <10% rated current. 3. Nominal Melting I2t measured at 1 msec. opening time. For other I2t data refer to chart. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized and with fuse mounted on board with 3oz Cu trace. 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. Resources Accessories Samples Additional Information
