贮存条件

KEMET

T491、T492、
T493、T494、T495、T496(MnO2)

Tantalum chipcapacitors should be stored in normal workingenvironments. While the chips themselves arequite robust in other environments, solderability 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 – reels may soften or warp, and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40 degrees C, and maximum storage humidity not exceed 60% relative humidity. In addition, temperature fluctuations should be minimized to avoid condensation on the parts, and atmospheres should be free of chlorine and sulfur bearing compounds. For optimized solderability, chip stock should be used promptly, preferably within 3 years of receipt.
片式钽电容器应存放在正常的工作环境中。片式钽电容极片本身在其它环境中比较活跃,因此暴露于高温、过于潮湿、腐蚀性的环境下或长期存放都会减低其可焊性。另外,高温会损坏包装材料——卷轴会软化或弯曲,磁带外壳压力会增大。KEMET建议最高储存温度不超过 40℃,最高储存湿度不超过60%(相对湿度)。还有,温度波动必须最小化以避免部件冷缩,也应避免有氯化物和硫化物的环境。为使其可焊性达到最优化,片式钽电容应及时使用,最在到手的三年之内使用。

T520、T525、 T530(polymer)

Conductive polymer series (T520, T525, T530) are shipped in moisturebarrier bags with a desiccant and moisture indicator card. These series areclassified as MSL (Moisture Sensitivity Level 3). Upon opening the moisturebarrier bag, parts should be mounted within 7 days to prevent moistureabsorption and outgassing. If the 7 day window is exceeded,the parts can bebaked per the instructions on the bag (168 hours at 40±5oC) Polymer chip capacitors should be storedin normal working environments. While the chips themselves are quite robustin other environments, solderability will be degraded by exposure to hightemperatures, high humidity, corrosive atmospheres, and long term storage. Inaddition, packaging materials will be degraded by high temperature - reelsmay soften or warp, and tape peel force may increase. KEMET recommends thatmaximum storage temperature not exceed 40 degrees C, and the maximum storagehumidity not exceed 60% relative humidity. In addition, temperaturefluctuations should be minimized to avoid condensation on the parts, andatmospheres should be free of chlorine and sulfur bearing compounds. Foroptimized solderability, chip stock should be used promptly, preferablywithin 1.5 years of receipt.

OxiCap

Tantalum and OXiCAP® capacitorsexhibit a very low random failure rate after long periods and from this thereare no. All capacitors will withstand any environmental conditions withintheir ratings for longer periods given in the detail specifications. Storagefor longer periods under high humidity conditions may affect the leakagecurrent of resin protected capacitors. Solderability of solder coatedsurfaces may be affected by storage of 2 years. Recommended storageconditions:Temperature:15℃-35℃ Humidity:45-75% RH

1) It is desirable to storeTantalum Capacitors under standard state*.
As the properties andsolderability of capacitors could be affected over the standard state*, keepthe temperature and humidity under the above conditions and if stored overthe above conditions, it is preferable to store for only 1 year.
2) Please keep away from thedirect ray of light.
3) Please do not apply excessiveforce to the capacitor's body and especially to the lead terminals.
4) Please do not apply shock andvibration by dropping or squeezing the capacitors.
*Condition of standard state :5~35°C,45~85%RH

The solderability of thecapacitor may be degraded by humidity. Store the capacitor at roomtemperature (−5 to +40C)andhumidity (40 to 60% RH).Nichicon
• It is desirable tostore capacitors at normal temperatures 35°C Max. and normal humidity.
• Keep out of directsunlight.
• Don't apply forceto capacitor's body and especially terminal.
• Don't apply shockand vibration by dropping etc.
• It is preferableto store for no more than 1 year under the above condition.
(when you use partthat has been stored more than 1 year, please contact your local sales officeto have assistance)
It is necessary to set anenvironment to prevent a trouble at the time of soldering by the degradationof solder ability or moisture's getting into the molding resin when POSCAPare stored.

POSCAP

(1) Please make the storage ofPOSCAP sealing up in the reel and storage bag.
(2) Do not store the POSCAP athigh temperature and high humidity.
Store it in a location that isnot subject to direct sunlight, has temperatures less than 35C (Generally 15 to
35C), and relativehumidity less than 75%RH(45 to 75%RH) generally.
(3) The storage period is oneyear or shorter under the condition that it is sealed up in the storage bag.
(TQC series : 6 months)
(4) Do not store the POSCAP indamp conditions such as with water, salt spray, or oil spray, and dewcondensation.
(5) Do not store the POSCAP inplaces filled with noxious gas (hydrogen sulfide, sulfurous acid, nitrousacid,
chlorine, ammonia, etc.).
(6) Do not store the POSCAP inplaces susceptible to ozone, ultraviolet rays and radiation.
(7) Please unseal storage bagjust before mounting and be conscious that POSCAP not remain. When
remainder occurs reluctantly,return them to storage bag once again and, please seal the unsealing division
by adhesive tape etc., includingdesiccants.
(8) The moisture level of POSCAPis the following.
(For questions regarding TQCseries, please ask separately.)

EPCOS

 

Capacitors with solidelectrolyte may be stored at temperatures down to -80℃.Theupper storage temperature must not exceed +85℃(for blister tape the temperature limit is +40℃)Thestorage conditions should not exceed +40℃and70%R.H.A dry pack is useful to prevent the effects of humidity.

钽电容器应避免超温使用。超温下会使材料的性能发生改变,因电容器使用的各种材料热膨胀系数不同,可能产生内部应力而使电容器失效;电容器在高温下长时间储存,可能会产生内部热应力导致失效。因此,必须在标准规定的温度范围内贮存和使用。
