8 \ VISHAY Industry 4.0 and Beyond The Industry Leverages ISM Radio + 5G for Advancements Whether it's a status message from a Euro pallet, monitoring goods for motion, or a certain process state, the key performance indicator in these applications is the ability to maintain the lowest possible power consumption in sleep mode until an alarm state for incorrect handling— dropping goods or unloading them roughly—actually occurs. In addition, the active movement of assets that shouldn't normally be moved would be stored as an error in the sensor or output as a radio message. Such an alert may not be required for months or even years, so the sensor must have enough energy to execute its scheduled activity, without aging effects or drift impairing its functionality. ENYCAP™: The Best of Both Worlds in a Hybrid Solution At 50Wh/kg, the energy density of an ENYCAP capacitor is considerably greater than the maximum value of other supercapacitors. The nominal voltage of an ENYCAP device is always a multiple of 1.4V and useful down to 0.9V per cell. Two devices in series will accommodate the typical voltages of microcontrollers or populated sensors. Three 1.4V cells connected in series can be used to replace a lithium-ion cell yielding exactly 4.2V to 4.35V. This version can also be charged with a typical lithium charging IC, a factor that considerably reduces the hurdle for new technological developments. The 4F versions can replace a button cell with a 6.8mm diameter (comparable to the SR621SW, SR612FE, or MS614/21SE cells), while the 15F versions have 12mm diameters (comparable to the SR44 or CR1225). Together with the 90F version, designers can then choose from absolute energy values ranging from 4.4Ws to 115Ws (~1.1mAh to ~30mAh) per 1.4V cell and voltage ranges from 1.4V to 8.4V. "The goal here is to eliminate the situation where battery replacement is required frequently to avoid system malfunctions or failures in the event of an emergency." "Radio standards that use short- burst transmissions are the best choice because the low ESR of the ENYCAP capacitors can be used to full advantage in the first milliseconds." Figure 2: 4F Overview: 4F/4.2V three-cell version, specified at a conservative 22.5Ω internal resistance in the datasheet, exhibits a voltage drop of only 0.7V at room temperature and pulse loading.
