Leadtime trends

Leadtimes are generally stable with a three-week increase in the leadtimes for general-purpose surface-mount resistors. Extended leadtimes are still being shown for ceramic capacitors in 0201 and 0402 cases as well as axial electrolytic capacitors. Alternatives can be recommended for the values of these capacitors which are on longer leadtimes.

Metal price trends

A small but general rise in pricing has been seen across most base and precious metals which follows a drop in prices which occurred around March to May 2020. The previous drop in silver prices has been followed by a sharp rise which is beginning to fall.
