What is MSL?

The Moisture Sensitivity Level (MSL) is an established electronic standard, established by JEDEC, used to define the period of time  which a moisture sensitive component (PCBs included) can be exposed to ambient temparature.

According to this standard, there are eight levels of moisture sensitivity, pls see below photo:
The definition of Floor Life is the allowable period of time storage at less than 30℃, 60%RH.

HONGDA Capacitors is specialized in Capacitors, Inductors, Resistors manufacturing, with 20+ years experience.
for our MLCC, Inductors, MSL=1 valuated by our company, indicates they are not moisture sensitive components.
