Thru-Hole vs. Surface Mount The thru-hole chip is not only thicker than the surface mount chip, but it eliminates the real estate underneath because the pins stick through.

As through-hole components are supplanted by their surface-mount equivalents, we’re beginning to see the departure of once-common component form factors.

Although the through-hole portion of the varistor market is growing at a much slower rate than its surface-mount counterparts, makers of leaded varistors anticipate sales increases this year in the 5% ...
