Main characteristic curve

Matters needing attention

1. This product is packed with environmentally friendly materials, 50 pieces of small packaging, 200 pieces of large packaging;
2. Avoid storing the product in humid and high temperature environment;
3. It should be stored in a non-erosive gas, otherwise it will lead to oxidation of the tin layer and decrease of weldability.
Therefore, after opening the package should be used as soon as possible
4. Working environment humidity ≦95%
5. Welding time as short as possible; Soak the tin liquid (Sn63 Pb37) at 230℃ to 5mm away from the CdS photoresistor body, and maintain 3-5s.
6. Note that the lead welding position should be more than 4mm away from the ceramic base.

Packing and Shipping:

Light dependent resistors (LDRs) are typically supplied in individual packaging for ease of handling and to protect them from dust and dirt. The packaging should be able to protect the LDR from physical impact, moisture, and static discharge. We recommend that each LDR be placed in a static shielding bag and then individually packaged in a small box.

When shipping, the LDRs should be placed in a sealed, padded container to protect them from the elements. We recommend using an air cushion or bubble wrap to provide additional protection. The container should be marked with fragile labels and a "Do Not Stack" sign.
