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.

Note

(1) For T27, lead (Pb)-free capacitors tp = 30 s

Notes

• T50, T51, T52, T55, T56, 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.
