This SMD Resettable Fuse (PPTC) uses the 1812 package and comes in a 100-piece lot. Model: 1812. Current ratings available: 0.05A, 0.1A, 0.2A, 0.5A, 0.75A, 1.1A, 1.5A, 1.6A, 2A, 2.6A, 3A. Material: PPTC PolySwitch self recovery fuse. Color varies by rating to help identification. Key benefits - Self reset after fault: interrupts overcurrent and automatically returns to normal when the fault is cleared, reducing downtime and maintenance. - Compact 1812 package: suitable for dense surface mount PCB layouts without redesigning the board. - Wide protection range: multiple current ratings allow precise protection for a variety of small power circuits. - Durable and reliable: polymer PTC material delivers repeatable protection over many fault cycles. - Easy identification: color coding helps quick rating recognition during assembly. What it protects and how it helps - Prevents damage from short circuits and overloads in compact devices while keeping downtime low. - Keeps USB chargers, power banks, LED drivers, and small power adapters safe from overcurrent conditions. - Ideal for microcontroller boards and portable electronics where space is limited and serviceability matters.
