Fig.5 Reel. Storage requirements These storage requirements should be observed in order to ensure the soldering of the exposed electrode: * Maximum ambient temperature shall not exceed 40 C. Storage temperature higher than 40 C could result in the deformation of packaging materials. * Maximum relative humidity recommended for storage is 70% RH. High humidity with high temperature can accelerate the oxidation of the tin-lead plating on the termination and reduce the solderability of the components. * Products shall not bestored in environments with the presence of harmful gases containing sulfur or chlorine.
