Descriptions:

The PT6312BLQ is a resettable PTC thermistor designed for overcurrent protection in electronic circuits. It provides reliable circuit protection by increasing resistance when excessive current flows, then automatically resets when the fault is removed.

Features:

  • Resettable Overcurrent Protection – Returns to low resistance after fault removal.
  • Fast Trip Time – Responds quickly to overcurrent conditions.
  • Compact SMD Package – Suitable for space-constrained PCB designs.
  • Wide Operating Temperature Range – Functions reliably in harsh environments.
  • Low Initial Resistance – Minimizes power loss in normal operation.
  • RoHS Compliant – Meets environmental safety standards.

This device is commonly used in power supplies, battery packs, and consumer electronics for circuit protection.
