. The IPC-7351 mathematical model includes the Terminal Lead Width and the Width Tolerance. This will always result in a pad size greater than the Terminal Width

. For capacitors, murata also recommends making the pad smaller than the width, mentioning that this reduces stress: https://www.murata.com/en-us/support/faqs/products/capacitor/ceramiccapacitor/mnt/0008 Other manufacturers of similar-sized inductors propose more reasonable looking footprints: https://media.digikey.com/pdf/Data%20Sheets/Samsung

0.15 mm (6 mils). The big issue is the pad annular ring. The fab shop will add 3 - 4 mils to the finished hole size. Then you must consider drill drift and layer to layer tolerance of 3 mil
