Soldering Condition
1、 Do not dip the capacitor into melted solder；
2、 Do not flux other part than the terminals；
3、 If there is a direct contact between the sleeve of the capacitor and the printed circuit pattern or
4、 a metal part of another component such as a lead wire, it may cause shrinkage of crack；
5、 If the application is for extended use, understand and manage the soldering characteristics to avoid
6、 abnormal current caused by a contact failure between the capacitor and the PCB；
7、 Please refer to product specifications about other notes。
Cautions For Use
（1）The problem of using different batches of supercapacitors
The recommendation soldering conditions of the product in which flow soldering is possible are as graph。
Caution for Using aluminum Electrolytic Capacitors：
When using supercapacitors, we recommend that using the same batch of products, and don’t mix up different batches
of products.
（2）The polarity of super capacitor
Unlike ordinary electrolytic capacitor or battery,the material of positive and negative polarity of super capacitor is same,
so theoretically super capacitor has no polarity; the polarities marked on super capacitor are established by manufacturers in
the production process, when the polarities are used reversely in short-term, it won’t cause substantial damage on capacitor,
and it can be used normally after adjusting to the right polarities. But if reversely use for a long time,the life of super
capacitor will decay quickly.
（3）Super capacitor charging information
To charge a super capacitor requires DC voltage that no more than the rated voltage.It can be charged by a variety of
methods such as current limit, constant current, constant power, constant voltage ; When charging, the super capacitor may
Page 11
BCE Series
（5）Operating temperature and product
（6）Transport and storage
lower the voltage of charging power supply until the capacitor is full to maintain voltage balance.
（4）Internal resistance and capacitance of super capacitor
In the process of charging and discharging, super capacitor’s IR drop caused by inner resistance will leads to lose of
efficiency of capacitor charging and discharging, so the size of capacitor determines the quality of capacitor to some extent;
Due to the internal resistance of the super capacitor is higher than normal capacitors, so in the process of charge and
discharge by AC circuit or high frequency circuit, super capacitor will become heating, and this cause life decay quickly,
that’s why super capacitor only commonly used in DC circuit.
Compared with ordinary capacitor, super capacitor has greater time constant τ , so the charge and discharge time is
longer; also because of this,it is not suitable for working with continuous large current frequently as it can cause performance
decay rapidly. The frequency characteristic of super capacitor is: the response time of positive and negative ions in carbon
electrode pore is longer, so the capacity appears very small. It is not allowed to measure super capacitor by using equipment
for testing common capacitors and AC measuring methods, it should be measured by methods for measuring battery for mAh.
Generally,When BIGCAP®supercapacitors work at rated voltage and low temperatures, the leakage current will be
less ,the standby time and life will be longer . On the contrary, under the condition of rated voltage and higher temperature,
the leakage current increases, the standby time is shortened, and the life is shortened. When the operating temperature is
certain, the life will increase when working at the rated voltage.
Should prevent products be affected with damp in product transportation,;The storage temperature should be - 30 ℃
to 50 ℃, relative humidity less than 60%, the maximum humidity no more than 85%, otherwise it will cause degradation of
capacitor performance or rust.
（7）Installation and welding
When super capacitors are used for double-sided circuit boards, must pay attention that the joint should not contact
Page 12
BCE Series
Try not to wire
the capacitor, otherwise it will lead to short circuit, over-voltage and damage of capacitor. During the process of installation
and after installation, do not twist or tilted the capacitor, do not be forcibly pull the wires. Capacitors should be welded after
cutting off and bending the leads. In the welding process, pay attention to avoid overheating of the capacitor ( for a 1.6 mm
thickness printed circuit board, the welding temperature should be 260 ℃, time is not more than 5 s), circuit board and the
capacitor should be clean after welding.
（8）The judgement of short circuit of Super capacitor
When short circuit, the capacitor can not be charged and discharged. Adopt a dc voltage between the positive and
negative electrode of capacitor, if the voltage does not rise,then we can determine short circuit occurs; when using a
multimeter to judge,when charging a new capacitor ,it is a normal phenomenon that ohms shift (short circuit shift) display
short circuit state, at this time, we can not make sure whether the capacitor is short circuit or not, we should observe
whether the resistance value is increased, an increasing on resistance value means no short circuit occurs.
（9）Use in series and parallel
When same super capacitors used in series, the total voltage = capacitor number x capacitor voltage ; The total
capacitance =single capacitor capacitance /capacitor number; Total energy = capacitor number x single capacitor’s
capacitance; total resistance = capacitor number x single capacitor’s resistance.
There is a voltage balance problem when 3 pcs or above capacitors used in series,so an equalization circuit is required
to ensure the capacitor will not over-voltage in long term use process, as over-voltage will cause decay and damage of
capacitor. Different specifications of the super capacitor cannot be used in series.
Super capacitors in different capacitance value can be used in parallel, theses capacitors should be charged by the same
voltage, but should pay attention to the current balance problem between the capacitors and mutual isolation, to avoid
potential difference happened after discharge.
（10）Other problems please consult the manufacturer or refer to BIGCAP® super capacitor relevant technical data.
