Surface Mount Humidity Packaging:
All Riedon Surface Mount wirewound resistors have a Moisture Sensitivity Level (MSL) rating of 2 (1-year floor life).
Surface Mount parts are packaged in a Moisture Barrier Bag (MBB) with a Humidity Indicator Card and desiccant to
monitor and protect the parts from humidity. The MBB is marked with a Moisture-Sensitive Identification Label.
