If you want to know why electrolytic capacitor
explosion first you have to know what electrolytic capacitor is electrolytic capacitor is a capacitor, metal foil as the anode (
Aluminum or tantalum)
With the positive close to metal oxide film (
Alumina or tantalum pentoxide)
Is the dielectric, cathode by a conductive material, electrolyte (
The electrolyte can be a liquid or solid)
And other materials, because of the electrolyte is a key part of the cathode, electrolytic capacitor hence the name.
At the same time, electrolytic capacitor plus or minus is wrong.
Aluminum electrolytic capacitor can be divided into four classes: led linear aluminum electrolytic capacitor;
Ox horn type aluminum electrolytic capacitor;
Bolt type aluminum electrolytic capacitor;
Solid aluminium electrolytic capacitor application of electrolytic capacitors are polar electrolytic capacitor is usually in the power supply circuit or intermediate frequency, low frequency circuit of power supply filter, decoupling, such as signal coupling and time constant is set, the dc insulation effect.
Generally cannot be used for the ac power circuit, the dc power supply circuit for the use of filter capacitance, the anode (
With the positive at the connection of the power supply voltage, cathode (
Connected to the power supply voltage of the cathode at, not against, otherwise it will damage capacitors.
Nonpolar electrolytic capacitor is usually used in speaker frequency divider circuit, the TV S correction circuit and single phase motor starting circuit.
Electrolytic capacitor is widely used in household appliances and various kinds of electronic products, the scope of its capacity is larger, general is 1 ~ 33000 & mu;
F, rated voltage range of 6.
3 ~ 700 v。
The downside is dielectric loss (error, capacity,
The maximum allowable deviation is + 100%, -
, poor resistance to high temperature and long storage time to failure.
The polarity of the electrolytic capacitor, observed in the side of the electrolytic capacitor has -
Is negative, the + is positive, if not specified on the electrolytic capacitor is negative, can also according to the length of the pin it to judge, long feet is positive, negative short feet.
Electrolytic capacitor explosion reason 1.
Is the cathode by 2.
Actual use voltage higher than the electrolytic capacitor nominal pressure value 3.
Ripple in the circuit is too large. 4.
Using capacitance temperature is higher than nominal value 5.
6 capacitance itself quality problem.
After long time use the electrolyte decrease, dry, capacitance parameter changes.
is emerging as one of the most popular ac motor capacitor
, moving beyond its ac start capacitor benefits, with conclusive scientific evidence suggesting the positive role play in compressor start capacitor.
What are you waiting for? Don't you want to provide perfect support to dual start capacitor? If yes, so, switch to ac motor capacitor right away!
