Kevin P. FlemingI'm designing a small circuit board which will have an STM32 microcontroller.One document from STMicro says that the part must have two capacitors to filter the power supply, a 'ceramic' cap at 100nF, and a 'chemical' cap at 4.7uF.Another document says they should both be ceramic caps, and the Nucleo64 evaluation board (sold by STMicro) uses ceramic caps for both.Should I bother using a different cap for the larger value? If so, what qualifies as a 'chemical' capacitor, just electrolytics?<a href="https://mastodon.km6g.us/tags/Electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Electronics</a> <a href="https://mastodon.km6g.us/tags/Capacitors" class="mention hashtag" rel="nofollow noopener" target="_blank">#Capacitors</a> <a href="https://mastodon.km6g.us/tags/SchematicDesign" class="mention hashtag" rel="nofollow noopener" target="_blank">#SchematicDesign</a>
