2 milliohm current sense resistor for Buck converter...Supply issues

Hello,
We are doing a 200khz buck converter with the LTC3892 controller. It is Vin = 28VDC to vout = 1.5VDC and Iout = 17.1A. (pdf and ltspice sim attached)
The current sense resistor is 2 milliohms and dissipates 0.59 Watts.
We really wanted to use a 1.8 milliohm sense resistor, but couldn’t find any in stock, so we stuck with the 2milliohm, 2512 size sense resistor.
Can you confirm that in such low resistance sense resistors, (less than or equal to 2 milliohms) it is best to stick to values that are either 1 milliohm, 1.5 milliohm, or 2 milliohms, because outside of these values, they are very hard to find in-stock and lead times could be very long?

Also, 2512 type sense resistors are very thin and wide, and are prone to snapping with PCB vibration, but again, choosing a type of package resistor that is less likely to snap is a bad idea because they have such long lead times, do you agree.?

Here is a “metal plate” resistor which is more immune to board bending, but they are almost never in-stock, and very difficult to come by…

Not only are those types of resistors hard to find, they are also expensive.
And you are also correct on the PWB bending forces which can easily overstress it.

thanks, sorry, are you referring to the 2512's when you speak of the tendency to break physically, or the "metal plate" resistors?

The "metal plate" R's made of manganin, are by far the best, although a bit pricey in low volume, they can handle the worst type of overloads and shorts without damage or value change...

Thanks, and you agree that the metal plate ones are for more physically strong than the 2512 type?...more immune to board bending stress etc

D'oh as they are metal, they are far more mech rugged, needs a small hammer to upset them...
