Aluminum Electrolytic Capacitor Caution:
A) the polarity of electrolytic capacitors in use, should confirm the proper polarity, so as to avoid short circuit reverse polarity Er Shi-loop phenomenon, undermining capacitor or other parts, when the polarity of an unknown or unstable, please use the non-polarized capacitors .
2) The capacitance test range, electrostatic capacity and conditions for determination of tanδ value of 120Hz 25 ℃, leakage current value of the testing conditions at 25 ℃, rated voltage and time should be added after the determination.
3) The applied voltage can not exceed the rated working voltage, prolonged pressure overload will lead to reduction in capacitance, short circuit, damaged capacitor.
4) when using the capacitor ripple current can not exceed the maximum rated ripple current.
5) The capacitor should not be a sudden charge and discharge, due to the internal capacitors can cause a sudden heat damage.
6) When the ambient temperature exceeds the specified product temperature range should terminate your use.
If the capacitor prolonged storage, be sure to be placed in low-temperature environment, because the heat and humidity will cause the electrical characteristics and the partial oxidation of the welding wire. In the low-temperature environment, the use of capacitors can extend its life.
7) resistant to the following formula to calculate the ripple capacitor ESR value:
ESR value = Loss angle tangent / 2πFC10-6 f = frequency C = capacitance
8) Do not use electric soldering iron close to the capacitor body, so as to prevent casing deformation and cracking, when the capacitor immersion tin bath, the bath temperature of 230 ℃ ± 5 ℃, soaking time was 2 ± 0.5 seconds, to avoid the capacitor overheating damage.
9) Do not wire the capacitor is applied force, because force will be spread to the internal, resulting in leakage current, cut wire, leakage and other issues, such as: The following methods of operation 1. Capacitor ramp into the circuit board 2. Capacitor welding well and then twist around 3. capacitor pitch does not match with the PCB board 4. Hold capacitor has a good moving circuit board welding.
10) before and after the capacitor solder or printed circuit board solder cleaning before and after finishing, avoid the use of halogen hydrocarbon solvents in order to avoid damage of internal capacitors.
11) in order to avoid capacitor from time to time to rupture, 6.3 × 11mm and above all an additional aluminum explosion-proof.
12) product specifications based on JIS-C5141 Features (W pole), IEC384 production, processing and testing methods before and after experiment is based on JIS-C5102, IEC 384 specifications.
