High Inrush Current Withstand Time Delay Time Lag Surface Mount Chip Ceramic Fuses 12H1500D 32V 1206 SB 5A
Description
The 12H 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 150ºC. The general design ensures excellent temperature stability and performance reliability. The high I²t values, typical in the Littelfuse Ceramic fuse family, ensure high inrush current withstand capability
Features
Operating Temperature from -55ºC to +150ºC
100% Lead-free, RoHS compliant and Halogenfree
Suitable for both leaded and lead-free reflow / wave soldering

Notes:
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msec.
2. Nominal Resistance measured with < 10% rated current.
3. Nominal Melting I²t measured at 1 msec opening time.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
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. Devices designed to be mounted with marking code facing up.
