Product Q&A

Q:What is the main function of the TMRF03 Thermal Fuse Built-in Resistor?

It provides dual functions: stable resistance regulation for circuit operation and overtemperature protection to cut off the circuit automatically when abnormal heating occurs.

Q:How does the overtemperature protection mechanism work?

When the temperature rises beyond the rated activation temperature due to faults like short circuits, the fusible element melts rapidly, breaking the circuit connection to prevent damage or fire hazards.

Q:What are the typical applications for this component?

It is widely used in power supplies, household appliances, industrial equipment, telecommunication, and surge pulse protection where current limiting and thermal safety are required.

Q:Is this product RoHS compliant?

Yes, the product is RoHS compliant and lead-free.

Q:What customization options are available?

We offer customization from samples, designs, full customization, minor customization, and flexible customization. Specific parameters like power (1-10W) and tolerance (5%) can be adjusted.
