Aluminum Electrolytic Capacitor

Nantong Yi Pin Mechanical and Electrical Co., Ltd. is a state-level high-tech company which mainly produce and sales special aluminum electrolytic capacitor. The Snap In is primarily used for inverter, frequency converter, power source, wind power, PV(photovoltaic), military industry, locomotive, welding machine, etc. The manufacturing technology and management level are in domestic leading position and product quality has obtained the recognition from our customers. The main customers are: Emerson network power(Emerson),INVT, VEICHI,EURA DRIVES, such as domestic and international famous brands.

The company fully implements international standard ISO9001 and ISO14000.The product has got certificate such as UL, CE, ROSH and other international approvals.

    In product selection and related circuit design, please refer to the following informations:

1. Product performance and heat-resistant service life: The Snap In main series model and characteristics described as follows:

2.The application guidelines of aluminum electrolytic capacitor

2.1 Circuit design

First of all, please make sure the use of capacitor and installation conditions (must) whether meet our offer of technical specification conditions;

Working temperature and pressure ripple current must comply with the requirements of the technical specification;

In the circuit design, must choose to meet the requirements of the service life of capacitor capacitor;

Pay attention the aluminum electrolytic capacitor should not be against, will result in a design feature is not implemented and capacitor invalid in short time;

Over-voltage condition ensures that capacitors are not used; this will lead to a sharp drop of service time of the capacitor;

In the circuit design, the need to keep far away from heat capacitor, high temperature environment will lead to capacitor drop down; ;

Selection when switching power supply's output smoothing capacitor, in order to curb output ripple current, selected capacitor equivalent series resistance (ESR), the smaller the better, but using ESR capacitor with small output voltage of the abnormal oscillation may occur. To prevent oscillations of the output voltage, in general negative feedback on the line, phase need to keep 30 to 40 degrees leftover above. Phase leftover is to the lower limit of phase to-180 degree numerical, The smaller of the phase leftover, The performance differences of the component and Temperature changes caused the oscillation by the possibility of more. Through the use of the phase of the error amp line feedback correction, can prevent the output voltage of the oscillation.

2.2 To install

Once the capacitors installed on machines, and power on, even if the capacitor is discharge, but there is still electrical potential difference, do not use the hands or other parts of the body to contact ;

To discharge the capacitor, pls discharge with a resistance of 1k at least, do not use metal wires directly shorted the two terminals of a capacitor to discharge;

Before the load capacitor circuit board, must be confirmed polarity;

Don't let the capacitor drop to the ground; also do not use capacitor dropped.

The Snap In in the installation must be close to the circuit board (without leaving gaps between the bottom of capacitor and circuit boards);

2.3In the case of emergency

If you see from the smoke after the explosion-proof valve is open, please turn off the power immediately;

When the explosion-proof valve is open, do not face closer to the capacitor, because gives off gases temperature reaches more than 100 ° c, once the gas into the eyes, please washing immediately with clean water;

2.4 Store

Suggested the capacitor will be stored in the 5-30 °C and relative humidity less than 75% of the environment;

Storing capacitor leakage current could increase a year later, please contact the manufacturer to assist in handling the matter;

Confirm storage environment won't appear: water, water vapor, oil, salt water, acid and alkali gas, metal dust etc;
