  • What's Hysterisis?
    • As the strength of magnetic field(flux density) reaches Operation flux density(Bop), the output changes from High to Low. To prevent mis-operation(Chattering) around detected magnetic field, Brp is set to be smaller than Bop. The difference between Bop and Brp is called "Hysterisis."
  • What is MSL?
    • Short for Moisture Sensitivity Level, MSL is a JEDEC (Joint Electron Device Engineering Council) standard established for the purpose of preventing device failure due to volumetric expansion of atmospheric moisture introduced into the resin package of semiconductor devices during reflow.
      The floor life of IC packages, during which the components must be mounted and reflowed after opening the moisture-resistant packaging, is broken down into 8 MSL levels.
