The guidelines and examples presented here help in evaluating the optimal decoupling
capacitors for the nRF52840 SoC power supplies.
nRF52840 decoupling
The nRF52840 SoC includes integrated regulators that depend on off-chip decoupling capacitors.
nRF52840 capacitor selection
In the schematic design for the application, it is important to select decoupling capacitors with sufficient efficient capacitance for decoupling.
nRF52840 effective capacitance specification
The effective capacitance specification for nRF52840 consists of minimum, typical, and maximum values per each supply. Typical value is the target for nominal capacitance to be assembled on an application schematic. The minimum and maximum values denote the range in which the total effective capacitance must stay under all operating conditions as addressed in this white paper.
