Remark: 1)The pin dimension of the product outline drawing is the size before tinning (it will become larger after tinning), and the mounting hole size is the recommended design size of the PCB board hole. The specific PCB board hole design size can be mapped and adjusted according to the actual product. 

2)In case of no tolerance shown in outline dimension: outline dimension ≤ 1mm, tolerance should be ±0.2mm; outline dimension ＞ 1mm and ≤ 5mm, tolerance should be ±0.3mm; outline dimension ≤ 5mm, tolerance should be ±0.4mm. 3)The tolerance without indicating for PCB layout  is always ±0.1mm.
