Installation of supercapacitor
CAP-XX prismatic supercapacitor – Single cell
CAP-XX has 4 main package types for the prismatic line. From the smallest to the biggest they are:
Z, A, W and S. The A and Z packages are pin compatible. Pins are reversed between W/S
packages and the A/Z packages. Hence when installing a W or S package s
ingle cell, the
supercapacitor must be rotated 180
̊
as shown in figure 2 below. Please ensure that the active-
balance configuration jumper header JP12 is connected to GND as shown in red in the figure
below. This jumper is labelled:

CAP-XX prismatic supercapacitor – Dual cell
CAP-XX prismatic dual cells are installed in the same direction. Please ensure that the active-
balance configuration header is connected to the cell midpoint as shown in red in figure 3 below.

CAP-XX cylindrical cells
CAP-XX’s cylindrical products, the GY & HY series (xY), covers capacitance from 1F to 100F in
radial lead form.
The APPEB1012 board only fits single cell radial lead xY products however two single cylindrical
cells can be placed on the board in series to act as a dual cell. This gives access to the midpoint to
the active balance circuit. Our xY line currently has 6 different diameters but with only three
different pin pitches. The PCB through hole design for our cylindrical cells has one positive through
hole and three through holes for the negative pin. When installing an xY series cell, first place the
positive pin into the hole , then slide the negative pin of the cell into one of the negative
through-holes with the correct pitch. Figure 4 below illustrates this.
