Mersen PCS30-H - PCS series of semiconductor direct-mountable fuses address the need for electrical protection at the PC board. These fuses help PCB users/manufacturers reduce parts by eliminating clips and/or fuseholders and allowing automated assembly. PCS fuses are AC and DC rated and are extremely current-limiting. They will protect semiconductors, main frame boards, circuit breakers with low interrupting capabilities and other critical components. PCS fuses bring I2t protection, higher ampere, voltage and interrupting ratings and are UL Component Recognized.
