F28M36x Bill of Material R1.1 C9-C16

Uwe Marczinek

Hello,

where can I get this capacitors?

Maybe it is an error from TI, because the normal values for X7R/0402/16V ends at 100nF (Mouser, Digikey,....).

Or can I use the X5R dielectricum?

36	32	C9-16	8	470n			CAP CER 16V 10% X7R 0402

Dear Gautam,

thanks for the answer, but:

Yageo have only 6,3V with 470nF (page5 of the datasheet)

Best Regards

Uwe

Yes Uwe, I did notice that. What I wanted to indicate is; have a talk with Yageo distributors. I'm sure you might get a positive feedback.

Uwe,

Yes, X5R can generally work as a replacement for X7R. In general, both are very similar dielectrics with the major difference being operating temperature ranges.

Because the signal across the capacitor is ~1.2V in this design, you could also comfortably move down to a 10V rating on the capacitor and still have plenty of design margin.

Thank you,
Brett
