R20 Resistor Pin Details

Thought for 47 sec

I checked the project and R20 is a generic 500 Ω, 0603 resistor, not a manufacturer-specific part.

Result

I could not find an exact datasheet for R20, because it does not have an MPN assigned. The web results only turned up generic 0603 chip resistor families, not a datasheet for this exact placed part.

Pin	Schematic pin number	What I can confirm
P1	1	One terminal of the resistor
P2	2	The other terminal of the resistor

Important limitation

Because R20 is a generic part with no exact datasheet, I can’t accurately give datasheet-derived:

pin function descriptions beyond “terminal 1” and “terminal 2”
input/output characteristics
special usage constraints like max voltage, power rating, tolerance, tempco, or pulse limits

For a generic resistor, the two terminals are typically interchangeable, but I’m not going to present that as a datasheet fact unless we first assign a real manufacturer part.

If you want the full pin-by-pin datasheet answer

I can help you:

find a real 0603 500 Ω resistor MPN
assign it to R20
then extract the exact datasheet details for each terminal, plus power, voltage, tolerance, and usage notes

If you want, I can next find a suitable real replacement part for R20 and give you the proper datasheet-based breakdown.
