MC33157

MC33157 is a rectangular radial PTC resettable fuse rated at 30V DC, designed to hold 900mA during normal operation and trip at 1.8A within approximately 5.9 seconds. In the event of overcurrent, it provides effective protection before automatically resetting once conditions stabilize, making it ideal for low-voltage circuit safeguarding.

• UL approved
• Auto-resettable after fault, eliminating the need for fuse replacement
• 900mA hold / 1.8A trip current in ~5.9s provides balanced protection for low-voltage circuits
• Handles surge currents up to 100A, safeguarding against inrush spikes
• Compact rectangular through-hole design for easy PCB integration
• Performs reliably from –40°C to +85°C, ensuring durability in diverse environments
