# Can someone verify the hole diameter is correct?

I'm looking at this current sensor (datasheet)

I'm a little confused at this notation for hole size.

Pin 5 and 6 have a diameter of 0.6mm while pin 1, 2, 3, 4 have a diameter of 0.25mm ? Is that correct ?

If someone could also explain what this format is "4-0.25x0.5". I've never seen this type of notation before.

Thanks!

edit

I think it could be 0.25mm x 0.5mm (length x width) since the pins look more rectangular vs circular for pins [1,4].

Pins 1-4 are rectangular (flat, stamped). Thickness 0.25mm, width 0.5mm, length 5mm. The nominal hole diameter is the length of the diagonal of the cross-section of the pin. $\sqrt { 0.25^2 + 0.5^2} \approx 0.56$ mm. Add an allowance. I would use a hole with finished diameter 0.81mm (or more).
