I have a question related to the measurement of the minimum external #air gap. The datasheet says 8 mm (min.) (table 4, page 7). It is measured from the input to the output terminals. When I measure the distance in the drawing of the wide Body (RI-16-1) package, I come to a value of 7.46 mm (worst-case-scenario).
The 7.46 mm results from the following calculation:
Minimum #distance between pin edges: 10 mm (see attached screenshot)
Maximum length of flattened area of pin: 1.27 mm (see attached screenshot)
10 mm - 2x(1.27 mm) = 7.46 mm
Could you please explain how the 8 mm are measured.
