About Surface mount technology :

• Can you hear the difference? - no, this is a " smelling the cork" discussion.
  Surface Mount, is more reliable, with a reject rate 100 time better than some error prone older components with greater failure rates.

• We use a combination of Thru-hole and surface mount technology for todays best performance and longevity

• Having said that , we are offering our older thru-hole model at the same price for those who want them, but with a warranty period of just 90 days. The warranty period of the op amps pictured is an astounding 5 years, and 10 days. Just let us know when you order.
