They support high current flow, provide good heat dissipation, and require wider and longer holes.<\/p>\n<p>&#8211; Wide pin holes: Used for flat, wide pins that carry large current. The holes are oblong (slotted) shape, not classified by pin quantity. The extra pin usually serves as a heat sink, ground pin, or control pin, providing more stable mechanical fixation.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-large wp-image-2045\" src=\"https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-1024x640.png\" alt=\"\" width=\"800\" height=\"500\" srcset=\"https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-1024x640.png 1024w, https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-300x188.png 300w, https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-768x480.png 768w, https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-1536x960.png 1536w, https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1-600x375.png 600w, https:\/\/preview.yhct.site\/d6cb8d6d\/wp-content\/uploads\/2023\/12\/N1-1.png 1920w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A customer asked me whether a taped insert with 3 pins or 2 pins is better.
