Conductive Polymer, Miniature, Undertab Solid Electrolytic Chip Capacitors

TEST

F38 series (Temperature range -55ºC to +105ºC)

Condition

At 40°C, 90 to 95% R.H., 500 hours (No voltage applied)

Capacitance Change ........... Refer to page 228 (*3)

Dissipation Factor ................ 200% or less of initial specified value

Leakage Current .................. 300% or less of Initial specified value

At -55°C / +105°C, 30 minutes each, 5 cycles

Capacitance Change ........... Refer to page 228 (*3)

Dissipation Factor ................ 200% or less of initial specified value

Leakage Current .................. 400% or less of initial specified value

5 seconds reflow at 260°C

Capacitance Change ........... Refer to page 228 (*3)

Dissipation Factor ................ 200% or less of initial specified value

Leakage Current .................. 300% or less of initial specified value

After application of surge voltage in series with a 1kΩ resistor at the rate of 30 seconds ON, 30 seconds OFF,

for 1000 successive test cycles at 85ºC (*2), capacitors shall meet the characteristic requirements in the table above.

Capacitance Change ........... Refer to page 228 (*3)

Dissipation Factor ................ 200% or less of initial specified value

Leakage Current .................. 300% or less of initial specified value

After 1000 hours’ application of rated voltage in series with a 3Ω resistor at 85°C (*2),

capacitors shall meet the characteristic requirements in the table above.

Capacitance Change ........... Refer to page 228 (*3)

Dissipation Factor ................ 200% or less of initial specified value

Leakage Current .................. 400% or less of initial specified value

After applying the pressure load of 5N for 10±1 seconds horizontally to the center of capacitor side body

which has no electrode and has been soldered beforehand on a substrate, there shall be found neither

exfoliation nor its sign at the terminal electrode.

Keeping a capacitor surface-mounted on a substrate upside down and supporting the substrate at

both of the opposite bottom points 45mm apart from the center of capacitor, the pressure strength is

applied with a specified jig at the center of substrate so that the substrate may bend by 1mm as

illustrated. Then, there shall be found no remarkable abnormality on the capacitor terminals.
