We continue to ask about filtering capacitors🙂 This time you can see C1 and C2 are filtering capacitors with different values connected together. C1 is 100 NF and helps with the high frequencies filtering on the power supply, C2 is with 10 uF and helps with higher current spikes with lower frequency. The picture above is the schematic. The Question is which one of these two capacitors C1 or C2 you should put closer to the IC1 pins?
You have time to re-tweet and/or answer until Monday 9th of November.
