1145HV(A)/1350HV High Voltage Fast-Acting Fuses

Eaton Electronics 1145HV(A) and 1350HV High Voltage Fast-Acting Brick Fuses provide reliable overcurrent protection up to 5A for high voltage applications. These surface-mount fuses are available in two sizes: 11mm x 5.0mm² [1145HV(A)] and 13mm x 5.0mm² (1350HV). The high voltage ratings and SMD package help reduce the required PCB space. The 1145HVA series components are AEC-Q200 qualified and ideally suited for xEV powertrains and applications.
