MC33174

MC33174 is a radial-leaded PPTC resettable fuse rated for 90V DC. It holds 400mA under normal conditions and trips at 800mA within approximately 3.8 seconds. This self-resetting fuse restores circuit protection automatically once the fault clears, ideal for safeguarding low-current electronics in telecom and industrial equipment.

• UL approved
• Self-resetting overcurrent protection eliminates fuse replacements
• 400mA hold / 800mA trip with ~3.8s response offers balanced fault response and circuit integrity
• Surge tolerance up to 40A provides robust defence against inrush currents
• Compact radial through-hole design with 5.1mm lead spacing fits tight PCB layouts
• Operates from –40°C to +85°C, ensuring reliable performance across diverse environments
