MC011423

MC011423 is a miniature 0603 SMD PPTC resettable fuse rated at 24V DC. It supports a nominal hold current of 40mA and trips at 120mA within approximately 1second. Once the overcurrent fault clears, it resets automatically, providing precise, compact overcurrent protection for sensitive low-current circuits in handheld, telecom, and industrial devices.

• UL approved
• Auto‑resettable after fault, no fuse replacement needed
• 40mA hold / 120mA trip (~1s), ensures fast, accurate protection
• Surge tolerance up to 40A, guards against inrush transients
• Tiny 0603 SMD package, perfect for high-density PCB designs
• Reliable from –40°C to +85°C, suitable for diverse environments
