can you help me estimate the inductance and resistance?

in a QFN 48 pin package, do you know its estimated inductance of the down bond wire? It's circled in the picture.

Thanks~

Ask Amkor. Or use FastHenry from Fastfieldsolvers to calculate it exactly from a 3D model.

I even used QFN24, and the inductance of down bond wire is about 0.5nH.
Buf for ditail, you must inquire the package provider.
