Nickel Barrier
Multilayer Ceramic Capacitors
Precaution For Handling
The multi-layer ceramic chip capacitors, may fall in a short circuit mode or in an open-circuit mode when subjected to severe
conditions of electrical, environmental and/or mechanical stress beyond the specified “Ratings” and specified “Condition” in the
Catalog and the Specifications, resulting in burnout, flaming or glowing in the worst case. So some common sense of application by
customer is necessary. Here the following article are some key points that need to take attention in application for customer reference
only:
Operating Conditions and Circuit Design
Operating temperature range
The specified “Operating Temperature Range” in the catalog is absolute maximum and minimum temperature rating. So in any case,
each the Capacitor shall be operated within the specified “Operating Temperature Range”.
Design of Voltage applications
The capacitors shall not be operated exceeding the specified “Rated Voltage” in the catalog. If voltage ratings are exceeded the
Capacitors could result in failure of damage. In case of application of DC and AC voltage to the capacitors, the designed peak voltage
shall be within the specified “Rated Voltage”.
Charging and Discharging Current
The capacitors shall not be operated beyond the specified “Maximum Charging / Discharging Current Rated” in the specification,
Application to a low impedance circuit such as a “secondary power circuit” are not recommended for safety.
Temperature Rise by Dielectric Loss of the capacitor
The “Operating Temperature Range” mentioned above shall include a maximum surface temperature rise of 20°C, which is caused by
the Dielectric loss of the Capacitor and applied electrical stress (such as voltage, frequency and wave form etc.)
It is recommended to measure and check “Surface temperature of the Capacitor” in your equipment at your estimated / designed
maximum ambient temperature.
Restriction on Environmental Conditions
The Capacitors shall not be operated and / or stored under following environmental conditions:
(a) To be exposed directly to water or salt water.
(b) To be exposed directly to sunlight.
(c) Under conditions of dew formation.
(d) Under conditions of corrosive atmosphere such as hydrogen sulfas, sulphurous acid, chlorine, or ammonia etc.
(e) Under severe condition of vibrations or shock beyond the specified conditions in the Specifications.
Secular change in Capacitance
(1) Peculiar characteristics of “Secular Changes in Capacitance” are observed in the Capacitors (Class 2 High Dielectric Constant
Temperature Characteristics “X7R” and “Y5V”. The “secular change” shall be considered in your circuit design.
(2) The Capacitance change, due to the individual characteristics of ceramic dielectric materials applied, can be recovered to the
each initial values at shipping by a heat treatment (140 to 150°C for 1 hour).
Design of Printed Circuit Board
Selection of Printed Circuit Boards
When the Capacitors are mounted and soldered on an “Aluminium’s Substrate has influences on Capacitor’s reliability against
“Temperatures Cycles” and “Heat shock” because of difference of thermal expansion dose not deterioration the characteristics of the
Capacitors.
There are some thermal expansion factor for different kink of PC board material as follows
