"junction" nach Englisch mit Beispielen - Kollokationen-Wörterbuch Englisch
- Industry good practice calls for 1,000 hours at a junction temperature of 125 C.
- This value is dependent on load current and junction temperature.
- When it is desirable to maintain junction temperatures below 125-150 C, copper/water heat pipes are typically used.
- For semiconductors, instantaneous junction temperature, rather than component case, heatsink, or ambient temperature is critical.
- Thus we can determine the junction temperature by passing a current through the diode and then measuring voltage developed across it.
- When the heatsink is not able to keep the temperature low enough, the junction temperature may rise quickly and uncontrollably, resulting in destruction of the device.
- It is highly necessary to keep the junction temperature below 120 C to run the LED's for maximum lifetime.
- The junction temperature will be lower if the thermal impedance is smaller and likewise, with a lower ambient temperature.
- Parameters of transistors depend on junction temperature.
- He used a galvanometer to measure current, and knew that the voltage between the thermocouple terminals was proportional to the junction temperature.
