Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Humidity Indicator Cards. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This humidity indicator card provides a quick visual indication of relative humidity inside sealed packaging for PCBs and other moisture-sensitive electronic components. The listed six-spot configuration covers 10%, 20%, 30%, 40%, 50%, and 60% RH levels.
Its indicator spots change from blue to pink as humidity increases, and the card is described as cobalt dichloride free. The card is intended for static humidity monitoring in moisture-barrier or vacuum packaging.
It can be placed inside the sealed package alongside a suitable desiccant, allowing receiving, storage, and quality-control personnel to inspect the enclosed humidity condition without electronic measuring equipment.
Supported application areas include PCBs, electronic components, automotive electronics, computer hardware, consumer electronics, electronic displays, industrial electronics, medical electronics, and military or aerospace electronics. The listed six-dot card size is 105 × 37 mm.
Packaging information identifies sealed vacuum inner packs, tinplate cans, and outer cartons or pallets. The product information also lists customization as available, a minimum order quantity of 10,000 pieces, a stated lead time of 10 days, and production capacity of 300,000 pieces per day.
For PCB packaging, the available guidance recommends placing one card inside the bag adjacent to the desiccant rather than directly on top of the desiccant packets.
The PCB should be packaged promptly after final inspection, and the moisture-barrier bag should be hermetically heat-sealed according to the bag manufacturer's sealing recommendations.
Desiccant quantity must be calculated for the selected bag, intended protection period, enclosed materials, and expected storage conditions.
Buyer confirmation is important because the supplied information includes multiple humidity-card chemistries, color-change systems, sizes, dot arrangements, packing counts, and standards. Before ordering, confirm that the quotation specifically covers the six-level 10%–60% blue-to-pink, cobalt-dichloride-free version.
Buyers should also request the applicable MSDS, REACH, RoHS, and standards documentation for the exact production configuration and verify current document revisions.
Confirm final artwork, dimensions, indicator tolerances, packing quantity, shelf life, storage requirements, inspection method, lead time, and pallet configuration in the purchase specification.
