FAQ
How is the rated power of RTP series resistors defined?
The rated power of RTP series resistors refers to the maximum power consumed by the resistor when operating continuously at 25°C ambient temperature without exceeding the specified temperature rise. In actual use, derating should be applied according to ambient temperature and heat dissipation conditions.
How to choose the appropriate resistor power?
When selecting resistor power, consider 2-3 times the actual working power as a safety margin. Also consider working environment temperature, installation heat dissipation conditions and other factors to ensure long-term stable operation of the resistor.
What are the installation methods for RTP series resistors?
RTP series resistors support multiple installation methods: 1) PCB mounting 2) Screw fixation 3) Heatsink mounting 4) Rail mounting. Please refer to the product user manual for specific installation methods.
What to do if the resistor temperature rise is too high during use?
If temperature rise is too high, it is recommended: 1) Check if actual working power exceeds rated power 2) Improve heat dissipation conditions, add heatsink or fan 3) Ensure installation environment is well ventilated 4) Consider using higher power resistor model.
How to judge the quality of resistors?
Judging resistor quality mainly considers: 1) Whether resistance tolerance meets requirements 2) Whether temperature coefficient is stable 3) Whether load life test meets standards 4) Whether it has passed relevant certifications (such as RoHS, REACH, etc.).
