| What is the terminology of thermistors? |
* Answer
| Rated zero-power Resistors R25 zero-power Resistors means that when the PTC thermistor value is measured at a certain temperature, the power consumption added to the PTC thermistor is extremely low, and the PTC thermistor caused by its power consumption is low.The change in resistance is negligible. The rated zero-power resistance refers to the zero-power resistance measured at an ambient temperature of 25 ° C. The minimum resistance RminThe number is defined as the relative change in resistance caused by temperature change. The larger the temperature coefficient, the more sensitive the PTC thermistor reacts to temperature changes. α = (lgR2-lgR1) / lge (T2-T1) surface temperature Tsurf surface temperature Tsurf isWhen the PTC thermistor is at a specified voltage and is in thermal equilibrium with the surrounding environment for a long timeThe number is defined as the relative change in resistance caused by temperature change. The larger the temperature coefficient, the more sensitive the PTC thermistor reacts to temperature changes. α = (lgR2-lgR1) / lge (T2-T1) surface temperature Tsurf surface temperature Tsurf isWhen the PTC thermistor is at a specified voltage and is in thermal equilibrium with the surrounding environment for a long timeThe number is defined as the relative change in resistance caused by temperature change. The larger the temperature coefficient, the more sensitive the PTC thermistor reacts to temperature changes. α = (lgR2-lgR1) / lge (T2-T1) surface temperature Tsurf surface temperature Tsurf isWhen the PTC thermistor is at a specified voltage and is in thermal equilibrium with the surrounding environment for a long time |
