PACKING AND STORAGE
Polymer capacitors meet moisture sensitivity level rating (MSL) of 3 or 4 as specified in IPC/JEDEC
®
J-STD-020 and are dry
packaged in moisture barrier bags (MBB) per J-STD-033. MSL for each particular family is defined in the datasheet - either in
“Features” section or “Standard Ratings” table. Level 3 specifies a floor life (out of bag) of 168 hours and level 4 specifies a floor
life of 72 hours at 30 °C maximum and 60 % relative humidity (RH). Unused capacitors should be re-sealed in the MBB with
fresh desiccant. A moisture strip (humidity indicator card) is included in the bag to assure dryness. To remove excess moisture,
capacitors can be dried at 40 °C (standard “dry box” conditions).
For detailed recommendations please refer to J-STD-033.
Notes
• T52, T55, and T58 capacitors are process sensitive.
PSL classification to JEDEC J-STD-075: R4G
• T54 and T59 capacitors with 100 % tin termination are process sensitive.
PSL classification to JEDEC J-STD-075: R6G
RECOMMENDED REFLOW PROFILES
Vishay recommends no more than 3 cycles of reflow in accordance with J-STD-020.
