Automotive SMD Resettable Fuses |
|
Qualified Per AEC-Q200 SpecificationLittelfuse introduced the nanoASMD, microASMD, and miniASMD product lines to the Automotive Surface-Mount Devices (ASMD) Resettable Fuses offering to support the miniaturization trend in automotive electronics and meet performance specifications for resistance, time-to-trip (TtT) and hold current at three temperatures (-40°C, 25°C and max T) as outlined in the automotive industry's AEC-Q200 standard for electronic components. Available in footprints from 1206 to 3425, TE's ASMD Resettable Fuses provide current ratings from 0.05 to 3.0A and voltage ratings from 16 to 60VDC. These devices provide overcurrent and overtemperature protection for Electronic Control Units (ECUs), I/O ports and traces, telematics and infotainment systems, and motor and motor control circuits. The nanoASMD, microASMD, and miniASMD product lines are rated from -40°C to +85°C. Littelfuse's Automotive SMD Resettable Fuses are Pb- and halogen-free, RoHS compliant and are compatible with high-volume SMD assembly processes.
