It's a partial inductance, similar to a piece of wire.
Unfortunately, the piece of wire would show different inductances with each different distance to the ground plane.
With 0402 chip, depending on where you define your reference planes, the pads may have a higher inductance than the chip itself. A meaningful analysis and measurement could be like this: Have e. g. a 8 mil trace on a 4 layer board, it has an inductance of about 0.5 nH/mm with a ground plane below. How does the inductance of a connection change, if you cut the trace and place a 0402 Jumper? In this case, the jumper may have virtually zero or even negative inductance, cause the overall inductance is reduced by the rather wide pads and jumper compared to the wire.
P.S.: Another realistic setup is a 20 mils/0.5 mm trace as reference. In this case, the said 0.1 nH are a good estimation for regular
wrap around mount of the jumper. The inductance can be assumed effectively zero for a reversed
flip-chip mount.
