Application Guidelines

1. Circuit Design

E n s u r e t h a t operational and mounting conditions

follw the specified conditions detailed in the catalog

and specification sheets.

1.2 Operating Temperature and Life Expectancy

(1) Expected life is affected by operating temperature.

Generally, each 10°C reduction in temperature

will double the expected life. Use capacitors at

the lowest possible temperature below the

maximum guaranteed temperature.

(2) I f o p e ra t i n g c o n d i t i o n s ex c e e d t h e m a x i m u m

guaranteed limit, rapid eIectrical parameter

deterioration will occur, and irreversible damage

will result.

Check for maximum capacitor operating tempera-

tures including ambient temperature, inter nal

capacitor temperature rise caused by ripple current,

a n d t h e e f fe c t s o f r a d i a t e d h e a t f r o m p ow e r

transistors, IC?s or resistors.

Avoid placing components which could conduct

heat to the capacitor from the back side of the circuit

board.

(3)The formula for calculating expected Iife at lower

operating temperatures is as fllows;

Aluminum Electrolytic Capacitor

1.3 Common Application Conditions to Avoid

The following misapplication load conditions will

cause rapid deter ioration to capacitor electr ical

p a r a m e t e r s. l n a d d i t i o n , ra p i d h e a t i n g a n d g a s

generation within the capacitor can occur causing

the pressure relief vent to operate and resuItant

leakage of electrolyte. Under extreme conditions,

explosion and fire could result. Leakinq electrolyte

is combustible and electrically conductive.

The vinyl sleeve of the capacitor can be damaged

i f s o l d e r p a s s e s t h r o u g h a l e a d h o l e for

subsequently processed parts. Special care when

locating hole positions in proximity to capacitors is

recommended.

(3) Circuit Board Hole Spacing

The circuit board holes spacing should match the

capacitor lead wire spacing within the specified

tolerances. Incorrect spacing can cause excessive

lead wire stress during the insertion process. This

may resuIt in premature capacitor failure due to

short or open circuit, increased leakage current,

or electrolyte leakage.

(1) Reverse Voltaqe

DC capacitors have polarity. Verify correct polarity

before inser tion. For circuits with changing or

uncertain polarity,use DC bipolar capacitors. DC

bipolar capacitors are not suitable for use in AC

circuits.

(4)Land/Pad Pattern

The circuit board land/pad pattern size for chip

capacitors is specified in the following table.

(2) Charqe/Discharqe Applications

Standard capacitors are not suitable for use in

repeating charge/discharge applications. For

charqe/discharqe applications consult us and advise

actual conditions.

[ Table of Board Land Size vs. Capacitor Size ]

(3) Overvoltage

Do not appIy voltaqes exceeding the maximum

specified rated voltages. Voltage up to the surge

voltage rating are acceptable for short periods of

time. Ensure that the sum of the DC voltage and

the superimposed AC ripple vo l t a g e does not

exceed the rated voltage.

(4) Ripple Current

Do not apply ripple currents exceeding the maximum

specified value. For high ripple current applications,

use a capacitor designed for high rippIe currents

or contact us with your requirements.

Ensure that allowable ripple currents superimposed

on low DC bias voltages do not cause reverse voltage

conditions.

1.4 Using Two or More Capacitors in Series

or Parallel

(1) Capacitors Connected in Parallel

The circuit resistance can closely approximate the

ser ies resistance of the capacitor causing an

imbalance of ripple current loads w i t h in the

capacitors. Careful design of wiring methods can

minimize the possibility of excessive ripple currents

applied to a capacitor.

Among others, when the size a is wide , back fillet can

not be made, decreasing fitting strength.

Decide considering mounting condition, solderability

and fitting strength, etc. based on the design

standards of your company.

(2) Capacitors Connected in Series

Normal DC leakage current differences among

capacitors can cause voltage imbalances. The use

of voltage divider shunt resistors with consideration

to leakage currents, can prevent capacitor voltage

imbaIances.

1.5 Capacitor Mounting Considerations

(1) DoubIe - Sided Circuit Boards

Avoid wiring Pattern runs which pass between

the mounted capacitor and the circuit board. When

dipping into a solder bath, excess solder may collect

u n d e r t h e c a p a c i t o r by c a p i l l a r y a c t i o n a n d

shortcircuit the anode and cathode terminals.

(2) Circuit Board Hole Positioning
