The TRC065 with PTC Resettable Fuses Through Hole P=5.1mm RoHS is a circuit protection device manufactured by TLC, a leader in component manufacturing. This particular component is a fuse that allows overcurrent protection in a variety of applications up to 5.1 mm in diameter. Once the current reaches an unsafe level, the fuse automatically trips and shuts off the current flow, preventing any further damage. Its PTC (Positive Temperature Coefficient) design will self-reset after the temperature drops below its melting point. The RoHS compliancy ensures that the component makes use of clean, safe materials and is free of dangerous toxins. It is an effective and cost-efficient means of protecting your electronics.
