9、e current Catalog of EIA a fan provides needed air flow. Air flow is measured using a hot-wire anemometer: air temperature is measured using an iron-constantan thermocouple which is particularly sensitive over the measuring temperature range of usual interest. The thermocouple is positioned between

10、the fan and he packaged unit. Measurements are typically made at room temperature and at a series of air velocities. Measurements are made with the assembly at the power in question, with the calibrated diode providing the value of the junction temperature. Example: where: TJ = junction temperature
