3.15 Moisture resistance. When tested as specified in 4.7.12, capacitors shall meet the following requirements:
Visual examination----------------------------- No mechanical damage. Marking shall remain legible.
Dielectric withstanding voltage
(when specified; see 3.1)------------------ As specified in 3.5.
Insulation resistance--------------------------- Unless otherwise specified (see 3.1), not less than 10 percent of the
initial 25 C requirement.
Capacitance
(when specified; see 3.1)------------------ Unless otherwise specified (see 3.1), capacitance change shall not
exceed 10 percent of the initial measured value.
3.16 Solderability. When capacitors are tested as specified in 4.7.13, the dipped surface shall be at least 95
percent covered with a new, smooth, solder coating. The remaining 5 percent may contain only small pinholes or
rough spots; these shall not be concentrated in one area. Bare base metal where the solder dip failed to cover the
original coating is an indication of poor solderability, and shall be cause for failure. In case of dispute, the percent of
coverage with pinholes or rough spots shall be determined by actual measurement of these areas, as compared to
the total area.
3.17 Resistance to soldering heat (all styles except CK22 and CK27). When tested as specified in 4.7.14,
capacitors shall meet the following requirements:
Insulation resistance--------------------------Not less than the initial 25 C requirement (see 3.1).
Capacitance-------------------------------------Change not more than +15, -5 percent from the initial 25 C
measured value.
Dissipation factor-------------------------------Shall not exceed initial limit.
3.18 Voltage-temperature limits. When capacitors are tested as specified in 4.7.15, the capacitance change shall
not exceed the applicable limits specified in table II. The capacitance value obtained in step C of Table VIII shall be
considered as the reference point.
3.19 Life (at elevated ambient temperature). When tested as specified in 4.7.16, capacitors shall meet the
following requirements:
Visual examination----------------------------No mechanical damage.
Insulation resistance--------------------------Shall be not less than the value specified (see 3.1).
Capacitance
(when specified; see 3.1)----------------Change shall not exceed 20 percent from the initial measured value.
Dissipation factor------------------------------Shall not exceed the value specified (see 3.1).
3.20 Marking. Unless otherwise specified (see 3.1), capacitors shall be permanently and legibly marked with the
PIN, the manufacturer's name or symbol, and the date code. Paper labels shall not be used. Other markings which
in any way interfere with, obscure, or confuse those specified herein are prohibited. The marking shall remain
legible after all tests.
