I honestly can't prove if it is a resister or an inductor. One thing I can say is it is a series device, not a shunt device. The cap is in fact a shunt.

That being said, it makes perfect sense that it is an inductor. The inductor and cap create an LC low pass filter, thus keeping the higher frequency noise from being radiated or conducted to other components or systems.
