The Lead Span is defined as the distance between the outer edge of the pins on one side and the outer edge of the pins on the opposite side. Also refer to Pitch, which is different.

There are two types of through-hole mounting components: the so-called axial and radial leads components.

  1. Axial lead components have the leads on both end sides of the component.
  2. Radial components have the leads on one end side of the component.
