w/Amendment 1
3.15 Life. When tested as specified in 4.6.12.1, capacitors shall meet the following requirements, as applicable:
a.
Visual examination - there shall be no evidence of corrosion or mechanical damage that will affect life or
serviceability.
At 25C:
b.
(1) Insulation resistance - Not less than the value specified (see 3.1).
(2)
Capacitance - Change not more than 1 percent of the nominal value or 0.5 pF, whichever is greater,
unless otherwise specified (see 3.1), from the initial value obtained when measured as specified in
4.6.5.
(3)
Dissipation factor - Shall not exceed the value specified (see 3.1).
3.15.1 Performance check. When tested as specified in 4.6.12.2.1, capacitors shall meet the following
requirements:
a.
Visual examination - There shall be no evidence of corrosion or mechanical damage that will affect life or
serviceability.
b.
Insulation resistance - Not less than the value specified (see 3.1).
c.
Capacitance - Change not more than 1 percent of the nominal value or 0.5 pF, which ever is greater,
unless otherwise specified (see 3.1), from the initial value obtained when measured as specified in 4.6.5.
d.
Dissipation factor - Shall not exceed the value specified (see 3.1).
3.15.2 Continuation test. When tested as specified in 4.6.12.2.2, capacitors shall meet the requirements
specified in 3.15.
3.16 Solderability. When capacitors are tested as specified in 4.6.13, the dipped surface of the leads shall be at
least 95 percent covered with a new, smooth, solder coating. The remaining 5 percent of the lead surface shall
show only small pinholes or rough spots; these shall not be concentrated in one area. Bare base metal and areas
where the solder dip failed to cover the original coating are indications 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 Terminal strength. When capacitors are tested as specified in 4.6.14, terminals shall not loosen or rupture,
and there shall be no permanent damage to the terminals or seal.
3.18 Temperature coefficient and capacitance drift. When measured as specified in 4.6.15, the temperature
coefficient and capacitance drift shall be within the limits specified (see 3.1).
3.19 Marking. Capacitors shall be marked with the type designation and the manufacturer's name or code
symbol. There shall be no space between the symbols that comprise the type designation. If lack of space requires
it, the type designation may appear on two lines. In this event, the type designation shall be divided between the
operating temperature range and capacitance symbols, as shown in the following example:
