Storage & Handling
The un-mounted storage life of a leaded ceramic capacitor is dependent upon storage and atmospheric conditions as
well as packaging materials. While the ceramic chips enveloped under the epoxy coating themselves are quite robust
in most environments, solderability of the wire lead on the nal epoxy-coated product will be degraded by exposure to
high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be
degraded by high temperature and exposure to direct sunlight – reels may soften or warp, and tape peel force may increase.
KEMET recommends storing the un-mounted capacitors in their original packaging, in a location away from direct sunlight,
and where the temperature and relative humidity do not exceed 40 degrees centigrade and 70% respectively. For optimum
solderability, capacitor stock should be used promptly, preferably within 18 months of receipt. For applications requiring
pre-tinning of components, storage life may be extended if solderability is veried. Before cleaning, bonding or molding these
devices, it is important to verify that your process does not affect product quality and performance. KEMET recommends
testing and evaluating the performance of a cleaned, bonded or molded product prior to implementing and/or qualifying any
of these processes.
