5 Electrical Characteristics
1. JEDEC document JEP157 states that 250 V CDM allows safe manufacturing with a standard ESD control process.
2. JEDEC document JEP155 states that 500 V HBM allows safe manufacturing with a standard ESD control process.
5.5 RF PowerConsumption Specifications
The power consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF
port. All transmitters’ measurements are based on a 50% duty cycle.

1. Device should operate in the frequency range allocated by regional regulatory authorities. Target operating frequency
range is configurable by software.
2. The typical value of ESP32’s Wi-Fi radio output impedance is different between chips in different QFN packages. For
ESP32 chips with a QFN 6×6 package, the value is 30+j10 Ω. For ESP32 chips with a QFN 5×5 package, the value is
35+j10 Ω.
3. Target TX power is configurable based on device or certification requirements.
