Multilayer Ceramic Chip Capacitors
Multilayer Surface Mount Ceramic Capacitors are constructed by screen printing alternative layers of internal metallic
electrodes onto ceramic dielectric materials and firing into a concrete monolithic body, then completed by application of
metal end terminations which are fired to assure permanent bonding with the individual internal electrodes.
Multilayer ceramic capacitors have various features such as large capacitance values in small sizes and excellent high
frequency characteristics.
Moreover, chip capacitors can be used on surface mount assembly equipment. Our fully integrated manufacturing and
total quality control systems ensure unprecedented high standards of quality and reliability.
Chip Capacitor Selection
Selection of the most suitable capacitor for any application is based on the following:
Dielectric Type
The choice of dielectric is largely determined by the temperature stability required.
COG (NPO)
Capacitance change with temperature is 0-30ppm/°C which is less than -0.3%°C from -55°C to +125°C. Typical capacitance
change with life is less than -0.1% for NPOs, one-fifth that shown by most other dielectrics. NPO formulations show no aging
characteristics.
X7R
Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change in non-linear.
Z5U
Despite their capacitance instability, Z5U formulations are very popular because of their small size, low ESL, low ESR and
excellent frequency response. These features are particularly important for decoupling application where only a minimum
capacitance value is required.
Y5V
Y5V formulations are for general purpose use in a limited temperature range. They have a wide temperature characteristic
of +22% - 82% capacitance change over the operating temperature range of -30°C to +85°C. Y5Vs high dielectric constant
allows the manufacture of very high capacitance value (up to 22MF) in small physical sizes.
Capacitance Value & Tolerance
Determined by circuit requirements. Note that chip prices decrease with lower capacitance value and looser tolerance.
Voltage
Determined by circuit requirements. Units are designed to exceed the withstanding voltage specification, i.e., the user need
not incorporate an additional safety margin.
Capacitor Size
Select the smallest unit permitted by the circuit constraints that provides the required capacitance and voltage rating.
Smaller units are generally less expensive : 0805 is the most economical size.
Capacitor Termination
Termination choice is largely determined by the chip attachment method. Silver-palladium is adequate for most applications
involving soldering or solder reflow.
Nickel barrier is standard and recommended for units exposed to repeated solder cycles, to minimize leaching of the
termination.
