1812L050/30PR.-LITTELFUSE-1812L050/30PR.-FUSE, RESETTABLE PTC, 1812, 30VDC, 500mA

The 1812L050/30PR.-FUSE, RESETTABLE PTC fuse from Littelfuse, designed to protect circuits from overcurrent conditions. It comes in an 1812 package size (4.5mm x 3.0mm), making it suitable for compact electronic devices. The fuse operates with a 30V DC voltage rating and offers 500mA of current protection. When excessive current flows through the circuit, the PTC material inside the fuse increases in resistance, limiting the current. Once the overcurrent condition is cleared, the fuse resets automatically to restore normal operation. This resettable functionality makes it ideal for consumer electronics and other low-voltage, low-current applications.
