https://devzone.nordicsemi.com/f/nordic-q-a/77762/reference-circuit-bomHi, We are currently implementing the nRF52840 in an upcoming product and we have a question regarding component selection for our configuration. I&#39;ve looked through the datasheet and resources - our design most closely matches reference circuiten-USTelligent Community 13Fri, 23 Jul 2021 12:12:50 GMThttps://devzone.nordicsemi.com/thread/321559?ContentTypeID=1Fri, 23 Jul 2021 12:12:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e4c3e525-3acd-4044-8c84-0e242ce1deb0Bendik Heiskel<p>Hi.</p> <p>Due to the summer vacations here in Norway we are currently short on staff, pardon the delay.</p> <p></p> <p>Changing to capacitors with different dielectrics should be OK, as long as the effective capacitance is within the specified limits. The effective capacitance is affected by AC and DC bias and temperature. For more information on the selection of decoupling capacitors please see our white paper on decoupling capacitor selection:</p> <p><a href="https://infocenter.nordicsemi.com/topic/nwp_030/WP/nwp_030/intro.html?cp=17_3">https://infocenter.nordicsemi.com/topic/nwp_030/WP/nwp_030/intro.html?cp=17_3</a></p> <p>It does also include a section specifically on the nRF52840, including the effective capacitance specifications for the chip.&nbsp;</p> <p></p> <p>Best regards,</p> <p>Bendik Heiskel</p><div style="clear:both;"></div>
