The SMD0603-005-24V with PTC Resettable Fuses 0603 RoHS is a small size, low-resistance chip manufactured by TECHFUSE. It is a surface mount device (SMD) that is designed for use in circuits with a maximum voltage of 24 volts. The fuses feature a permanent thermal cutoff which helps to protect the circuit from overcurrent and short-circuit situations. They are RoHS compliant and are ideal for higher-power, current-sensitive designs. The fuse can reset itself after the fault has passed and no further action is required. This helps to provide reliable protection from overcurrent and allows the circuit to remain operable at all times.
