MSL (Moisture Sensitivity Level)

This contains information on the MSLs (moisture sensitivity levels) as they relate to Sound Components. Please use it to determine the actual capabilities of the products you are considering.

However, since products compatible to reflow soldering are applicable to MSL, products dedicated to flow soldering, such as parts with leads, are not applicable.

Product Series MSL
Piezoelectric Sounders
PKLCS 1
PKMCS 2
  • MSL is a JEDEC standard, and is intended for the phenomenon where the cubical expansion generated by the gasification of the moisture included in the product due to the moisture absorption of the product and the reflow soldering during mounting, which results in failures. The level that expresses this risk is the "MSL" (Moisture Sensitivity Level).
