Fast oxidisation is a common issue related to high temperatures and the presence of oxygen during the convection reflow or wave soldering processes. The oxidisation may induce some degradation of metal surface and its environmental robustness, thus impacting the components and the electronic hardware lifetime.

Just as thermistors the varistor is fabricated from a compressed and sintered powder compound that consists of silicon carbide (SiC) or zinc oxide (ZnO). The ZnO varistor has superior characteristics and predominates today all manufacture. This section deals with ZnO varistors only.

Capacitor manufacturers have been adding capacity since 2017 and, while lead times for many parts could stretch, allocations for most parts, are not likely. However, it is unclear what the MLCC scenario will be and if buying conditions will turn from being a buyer’s market to a seller’s market. One thing is for sure. The MLCC market will be different in 2020 than it was in 2019.
