• Utilizes polymer positive temperature coefficient technology for reliable thermal response

Ptc Resettable Fuses Applications

• AC power supply input protection
• Consumer electronics line cord protection
• Appliance internal circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage rating matches the application's AC requirements, as this component is rated for 277 VAC rather than standard DC voltages. Confirm that the physical dimensions and lead spacing are compatible with the target PCB layout or wiring harness. Ensure the expected inrush currents do not exceed the device's trip threshold during normal operation to prevent nuisance tripping.

Ptc Resettable Fuses Selection Notes

Select this model when protecting AC lines where automatic restoration after fault clearance is required. Compare against standard fuses if maintenance reduction is a priority. Consider the higher initial resistance compared to low-resistance SMT variants if voltage drop is a critical design constraint. Verify thermal management capabilities given the 4.5 W power dissipation rating under fault conditions.

Ptc Resettable Fuses Part Context

This component belongs to the 0ZRV series of radial leaded PTC devices from Bel Fuse. This series is distinct from the company's DC-rated 0ZRS and 0ZRB lines, focusing instead on AC mains protection. The radial package allows for through-hole mounting, providing mechanical stability for line-connected applications.
