Matching capacitor on NTAG I2C plus Explorer Kit

andy_kim — Tue, 15 Jun 2021 06:14:37 GMT

Hello,

There is a 100pF matching capacitor (C1) on NTAG I2C plus Class 4 Antenna board.

Please refer to attached capture.

Could you let me know the part number of it to find out the specification (tolerance, temperature and rated voltage) to refer for our device?

and I'd like to know if there are recommended part list of capacitor for NTAG I2C plus solution.

Thank you,

Andy

Dear fangfang,

Thanks for your comment.

The file that you've attached is what I already checked out.

Unfortunately, it does not have the information what I would like to know

Is there any other document which describes about it below?

1. The part number of it to find out the specification (tolerance, temperature and rated voltage)

2. I'd like to know if there are recommended part list of capacitor for NTAG I2C plus solution.

Thanks you,

Andy

Dear fangfang,

Is my query in progress?

If there is no recommendations of specific characteristics for the matching capacitor, please let me know.

Thank you,

Andy
