[2523] SMT vs. Through Hole

Date: February 27th, 2019 | Comments : none | Categories: DIY.

All resistors have a certain amount of noise when current flows through them. Other factors then add more noise on top of that baseline, such as size, composition and quality of construction. No-name cheap smt resistors will have 200x more distortion than common 1/4w metal film through-hole resistors! Smaller smt resistors have more noise than larger sizes; example 0603 vs. 0805 smt sizes.

Good quality Panasonic or Susumu smt resistors will be better than cheap no-name resistors, and can be close to through-hole devices in performance. Dave Hill of Crane Song shared some real world measurements of resistors which clearly shows that there is a difference in performance between smt types vs through-hole. The diff is small but measurable.
