# Tolerance on SMD Aluminum Electrolytic Capacitors

I'm searching for some polarized surface mount device capacitors on lcsc.com and notice that they only have tolerances of $20\%$ tolerance devices in their catalog for this type of SMD device whereas the through hole counter parts have much lower tolerances. Is this normal for this type of device? My inherent feeling is that a $20\%$ tolerance is rather large.

edit:

The capacitors will be used in a Li-Po charge management circuit as shown below:

• +/- 20% is fairly standard for electrolytic capacitors, whether surface mount or through hole, certainly panasonic have the same tolerance on the smd and through hole parts for the same family. – Colin Aug 29 '18 at 9:11
• These are generally designed for a purpose where this tolerance is quite normal, although from memory I would have said the most I saw was -5/+20 – PlasmaHH Aug 29 '18 at 9:13
• Do you think it would be safe to assume that a data sheet application circuit would operate fine with a 20% tolerance? There is nothing in the application circuit that explicitly states tolerance of components. – Blargian Aug 29 '18 at 9:33
• What are the capacitors used for? – Colin Aug 29 '18 at 9:34
• @Colin I have updated the post with the schematic. They'll be used in a li-po battery charging circuit. – Blargian Aug 29 '18 at 9:46
