TCAN1042-Q1: The power rating for the termination resistor?

Hi 

We are not sure how big the power rating is needed for the termination resistor? A 0805 size 0.125W resistor good enough or what is the required power rating? thanks!

    PYTsai,

    In many applications and systems I've seen 1206 footprint used with 0.25W capability. In general, unless there is a fault condition, your termination resistors should be okay if they are 0805 or 1206 or bigger. Larger sized ceramic resistors can withstand more power dissipation.
