Part Number: TPS2373

Dear SIr,

my customer will use PD Class 5. RESITOR CLSB use 12K instead of 12.1K.

There are any side effect?

Hi Dexter,

I believe you are referring to 1.2k vs 1.21k instead of 12k and 12.1k

Class 0 current has a relatively wide range (0-4mA) compared to the 10 ohm difference which translates to ~20uA. So 1.2k ohms is okay.
