ST25R3916B AAT Variable Capacitors

[nick_s]

The LXRW Variable Capacitors used on the Reference Design ST25R3916-DISCO  / STEVAL-25R3916B are now marked as Last Buy by Murata. What alternatives are recommended for new designs?

 

Thanks,

Nick

Hello nick_s,

 

In terms of NFC Forum compliance, please have a look at our AN5896.  

It explains how to switch between reader and card mode matching without variable capacitors.

Otherwise please let us know if you have any specific questions.
