The TRA400 PTC Resettable Fuses with Through Hole P=5.1mm RoHS is an electronic component manufactured by TLC. This device provides protection from overcurrent faults in circuits. It is an ideal choice for use in consumer appliances, automated machinery, and other electrical systems when reliable circuit protection against overload and shorts is needed. This part features a high operating temperature range of -40°C to +105°C, and a 5.1mm PTC to fit in circuit boards and other small form factors. The fuse has a fast reaction time to detect faults and is self-healing and resettable, meaning it does not need to be replaced after a fault. It is RoHS compliant, ensuring that it is free from lead, cadmium, and other hazardous materials.
