So that the tag's IC doesn't get damaged.</P><P></P><P></P><P>Regards,</P><P>Ivan.</P></BODY></HTML> Tue, 18 Jul 2017 20:07:53 GMT https://community.nxp.com/t5/NFC/NT3H2111-vs-QI/m-p/678332#M2200 IvanRuiz 2017-07-18T20:07:53Z Re: NT3H2111 vs QI https://community.nxp.com/t5/NFC/NT3H2111-vs-QI/m-p/678333#M2201 <HTML><HEAD></HEAD><BODY><P>I just put in series decoupling capacitor (something about 1nF) after NFC coil.
