SNAP–IN MOUNT ALUMINUM ELECTROLYTIC
SI SERIES
SUBMINIATURE
(SI: Snap–in)
The SI Snap–in series subminiature aluminum electrolytic ca-
pacitors are especially suitable for applications requiring high ca-
pacitance, low cost, and very small size. In fact, you’ll find these
capacitors in some of the most demanding applications, from
precision medical electronics and automobiles to the newest
personal computers and disk drives.
They operate over a broad temperature range and are available
in either blister pack or bulk.
MECHANICAL SPECIFICATIONS
Marking:
Consists of series type, nominal capacitance, rated
voltage, temperature range, anode and/or cathode
identification, vendor identification.
Recommended Cleaning Solvents:
Chlorofluorocarbon solvents used to remove flux from
printed circuit boards can penetrate the capacitor end–
seals, cause corrosion when voltage is applied and ca-
pacitor failure. Avoid halogenated solvents and consid-
er these alternatives: Clean the capacitors with
water/detergent or cleaning solvents free of halogen
groups such as alcohol or terpene solution, or mount
the capacitor after board cleaning.
