Make the pH of the mixed liquid system=10,Stir at room temperature for 40 minutes, TLC monitors the progress of the reaction,After full reaction,Add 40ml of water, stir and crystallize,Suction filtration, wash the filter cake with 20ml water,Dry the filter cake under reduced pressure,Then ...
filter capacitor’s ESR dominates the output-voltage ripple, so the size of the output capacitor depends largely on the maximum ESR allowed to meet the output-voltage ripple specifications as follows: RMS VOUT × V − VOUT ( ) SUP IRMS = ILOAD(MAX) × VSUP V = ESR× ...
