5, 10, 60% RH humidity indicator. Dry-packed semiconductors with 5/10% RH low-level checks and a 60% RH checkpoint.
Description
MS051060 monitors 5%, 10% and 60% relative humidity inside dry-packed barrier bags. It is intended for moisture-sensitive semiconductors and surface-mount devices, combining low-humidity checkpoints with a 60% RH check.
The supplied 2004 manufacturer sheet identifies this design with J-STD-033B. It associates the 60% spot with MSL 2 components and the lower spots with MSL 2a–5a components. Use the printed instructions and the applicable packaging procedure when interpreting a card.
The sample card instructs users not to place it into a bag if the 60% spot is pink. The listed spot arrangement should not be confused with a maximum humidity card: the supplied JEDEC sheet does not establish an irreversible exposure record for this model.
Key specifications
- Indicator levels: 5, 10, 60% RH
- Card dimensions: 2 × 3 in
- Behaviour: 5/10/60% RH humidity indication

Applications
- Dry-packed semiconductors with 5/10% RH low-level checks and a 60% RH checkpoint.
- Visual inspection of desiccated barrier bags used for surface-mount component storage and handling.
Handling and storage
Keep unused cards sealed with desiccant in a cool, dry location. Avoid touching indicator spots and protect them from sunlight, water, steam and ammonia. Follow the card’s printed handling instructions and the packaging procedure for the components being protected.
