Product Ordering

This is just an demo for the document which you have to send for ordering the product

1. How to order :

a.) Series : refer to Specifications

b.) Rated Voltage :

      Voltage in Volts (V) is represented by a two digit code showing the real working voltage indicated as follows :

c.) Capacitance :

Rated  Capacitance in uF is represented by a three digit number. The first two digits are the significant figures of the nominal capacitance and the third digit indicates the number of zeros following these figures. The decimal Point is represented by the capital letter. Please refer to the example ;

d.) Size : Ex :

e.) Packing : B-Bulk             T-Tape

f.) Tolerance  :

Symbol of  W, T, Q, V, M, K and  J show special capacitance tolerance which are listed as follows.

2.) SURGE VOLTAGE :

The Surge voltage rating is the maximum DC over-voltage to which the capacitors may be subjected of short periods not exceeding approximately 30 seconds intervals of not more than five minutes.

Unless otherwise specified, the rated surge voltage of the electrolytic capacitors are as follows :

3. Polarity : Electrolytic capacitors have polarity, should be used for DC applicants

4. Ripple Current :

The ripple current is the RIMS value of the alternating   current component flowing through the capacitor. Maximum Ripple Current is a primarily function of the permissible temperature rise within a capacitor section due to resistive loss heating. Heating can occur as  a result of an A.C. current flowing through the equivalent series resistance and also due to DC leakage current, which is negligible. The temperature rise depends upon can size, ambient temperature and rate of   heat diffusion to surroundings and internal capacitor design. The sum of DC voltage and AC peak voltage shall not exceed the rated DC working voltage. The  maximum ripple current is defined as that which gives a steady state temperature difference between outer surface and central core of  capacitor of 10c and it is specified at 85c in other conditions of ambient temperature and frequency, the ripple current multiplied by following multiplier, can be calculated as maximum permissible ripple current.

AVOID TH FLOW OF EXCESSIVE RIPPLE CURRENT.

5. SAFETY VENT

Case diameters of  8mm and large for Radial type are designed with case venting.

6a.) SOLDERING :

1. Must be careful of temperature and time when soldering. Dip of flow soldering of the  capacitors should be limited at less than 260c and 10 seconds.
2. High levels of humidity will affect the solderability of lead wire and terminals. High temperature will reduce long-term operating life.
3. Following defective soldering affect the inside characteristics , such as increasing leakage current, short circuit, broken or wound of lead wires, and leaking electrolyte.

1. Parts Slan to the board after soldering.
2. Leads are greatly bent after Soldering.
3. Lead space on board differs from the original.

6b.) HANDLING AFTER SOLDERING :

1. Do not bend or twist the capacitors body after soldering on Printed Circuit Board (PCB).
2. Do not pick up or move PCB by holding the soldered capacitors.

7. LIFE TEST :

8. TAPPING SPECIFICATIONS :

9. DF STANDARDS :

For capacitors whose cap value exceeds 1000uF specifications of tan delta is increased by 0.02 for every addition of 1000uF and part of it.

10. ADDITIONAL INSTRUCTIONS :

1. Aluminum electrolytic Capacitors should not be stored in high temperature or where there is a  high level of humidity. The suitable storage conditions are 5c-35c and less than 75% in relative humidity.
2. Aluminum electrolytic Capacitors should not be stored in damp conditions such as water, saltwater spray or oil spray.
3. If the capacitors are stored or left unused for a long period, aging should be conducted at the rated working voltage before application due to increase of leakage current and decrease of voltage.
4. The electrolytic capacitor is not suitable for circuits in which charge and discharge are frequently repeated, otherwise the capacitance value may drop, or the capacitor may be damaged.
5. Do not apply excessive force to the lead wires or terminals, otherwise they may be broken or their connections with the internal elements may be effected.
6. Life of capacitors will be effected by solvents like Hologenated Alkali, Petroleum, Xylene, Acetone etc.
7. Do not expose the capacitors to the toxic gasses like sulfurous acid, Hydrogen sulfide, nitrous acid, chlorine or its compounds.
8. Provide appropriate hole spacing in the Printed Circuit Board to match the pitch of the capacitor.
9. The electrical characteristics of the capacitor vary with respect to temperature, frequency and service life. Design the device circuits by taking these changes into account.
10. Do not short-circuit the terminals of the capacitor by conductive objects. Always discharge the capacitors by proper resistor.
