Axial sense resistors for 750W Boost PFC

[cupoftea]

Hi,
The attached shows the two paralleled sense resistors (0.075R) that get used for a 750W Boost PFC. They are just axial thru hole.
Do you agree that low inductance , chip type current sense resistors are never needed for CCM Boost PFC?
The controller used is ML4800.
VAC is 240VAC

never is a long time

i see no reason to restrict anyone from using the components they want,
as long as the product is safe, meets spec, can be built, (schedule, cost, quality) etc etc

there will always be another opinion, another way of designing something,
a newer, fancier, smaller, etc, component

use what works

Resistor inductance can (and probably must) be systematical compensated by RC circuit.

Thanks, yes, there is a RC filter on the way in to the ML4800 chip. (30R/100n)

As you know, even if a SMD sense resistor is used, such filters are common aswell.

Would you agree that CCM Boost PFC's can actually better tolerate sense resistors with higher stray inductance compared to other types of SMPS's?
