100 µF e-cap
100 nF disc capacitor
The loudspeaker must not be
connected directly to the am-
plier but requires a capacitor.
Any capacitor consists of two
metal sheets insulated against
each other. The electrolyc
capacitor (e-cap) used here
contains aluminium sheets in a
conducve uid (electrolyte).
You have to pay aenon to
the mounng direcon as
the e-cap will be destroyed
when the polarity is reversed.
The negave terminal is the
shorter leg; it is addionally marked by a
white bar. The kit contains two idencal
e-caps with a capacitance of 100 microfa-
rad (100 µF).
There is another capacitor with only a
1000th of the capacitance of the e-cap,
i.e. 100 nanofarad (100 nF). The im-
printed number 104 means 100,000 pF
(picofarad). This component is a ceramic
disc capacitor and can be mounted in
any direcon.
