Ageing of Ceramic Capacitors

Tight Tolerance

Capacitor ageing is a term used to describe the negative,

logarithmic capacitance change which takes place in ceramic

capacitors with time. The crystalline structure for barium

titanate based ceramics changes on passing through its Curie

temperature (known as the Curie Point) at about 125ºC. The

domain structure relaxes with time and in doing so, the

dielectric constant reduces logarithmically; this is known as the

ageing mechanism of the dielectric constant. The more stable

dielectrics have the lowest ageing rates.

One of the advantages of Syfer’s unique ‘wet process’ of

manufacture is the ability to offer capacitors with exceptionally

tight capacitance tolerances.

The accuracy of the printing screens used in the fully

automated, computer controlled manufacturing process allows

for tolerance as close as ± 1% on C0G/NP0 parts greater than

or equal to 10pF. For capacitance value less than 4.7pF

tolerances can be as tight as ± 0.05pF.

The ageing process is reversible and repeatable. Whenever the

capacitor is heated to a temperature above the Curie Point the

ageing process starts again from zero.

Periodic Tests Conducted and Reliability Data

For standard surface mount capacitors components are

randomly selected on a sample basis and the following routine

tests conducted:

The ageing constant, or ageing rate, is defined as the

percentage loss of capacitance due to the ageing process of

the dielectric which occurs during a decade of time (a tenfold

increase in age) and is expressed as percent per logarithmic

decade of hours. As the law of decrease of capacitance is

logarithmic, this means that for a capacitor with an ageing rate

of 1% per decade of time, the capacitance will decrease at a

rate of:



Load Test. 1,000 hours @ 125˚C (150˚C for X8R).

Applied voltage depends on components tested



Humidity Test. 168 hours @ 85˚C/85%RH

Capacitance Measurements

Because of ageing it is necessary to specify an age for

reference measurements at which the capacitance shall be

within the prescribed tolerance. This is fixed at 1000 hours,

since for all practical purposes there is not much further loss of

capacitance after this time.

All capacitors shipped are within their specified tolerance at the

standard reference age of 1000 hours after having cooled

through their Curie temperature.
