High Reliability Chip - X7R
16Vdc to 10kVdc
A range of MLC chip capacitors in Stable EIA Class II dielectric
with special testing for long term reliability. They are designed
for optimum reliability; burned in at elevated voltage and
temperature, and 100% physically and electrically inspected to
ascertain conformance to strict performance criteria. Units may
be tested in accordance with MIL-PRF-55681, MIL-PRF-123, MIL-
PRF-49467, or customer SCD.
Designed for surface mount application with nickel barrier
terminations making them suitable for solder wave and reflow
solder board attachment as well as vapor phase attachment for
part sizes 2225 or smaller. Silver-palladium terminations are also
available for hybrid use with conductive epoxy.
Class II X7R chips are used as decoupling, by-pass, filtering and
transient voltage suppression elements and exhibit +/-15%
temperature coefficient and predictable variation of electrical
properties with time, temperature and voltage.
They find application for High Reliability use such as medical
implanted devices, aerospace, airborne and military use as well
as consumer uses requiring safety margins not attainable with
commercial products.
Standard EIA case sizes and available C/V values are listed below
- special sizes, thicknesses and other voltage ratings are available;
please contact the sales office for information.

Technical Summary
W
Technical Information
Novacap provides application notes throughout this catalog as
a guide to chip selection and attachment methods. Refer to the
Novacap Technical Brochure found at www.novacap.com for
more details. This technical information includes the nature of
capacitance, dielectric properties, electrical properties, classes
of dielectrics, ferroelectric behavior, test standards, and high
reliability test plans. Please do not hesitate to contact the sales
office for any product or technical assistance.
Capacitor Size
Size availability is based primarily on capacitance values and
voltage rating. Smaller units are generally less expensive.
Because mass affects the thermal shock susceptibility of chip
capacitors, size selection should consider the soldering method
used to attach the chip to the board. Sizes 1812 and smaller
can be wave, vapor phase, or reflow soldered. Larger units
require reflow soldering.
Chip Selection
Multilayer capacitors (MLC) are categorized by dielectric
performance with temperature. The Temperature Coefficient
of Capacitance describes the variance of capacitance value with
temperature. The choice of components is therefore largely
determined by the temperature stability required of the device
and the size necessary for the desired capacitance value and
voltage rating.
Packaging
Units are available reeled, in waffle pack, or bulk packaged. Bar
coded labels are standard for reeled and bulk packaging.
Primary Dielectric Types
T
MB
C0G/NP0:
Ultra stable Class I dielectric, with negligible dependence of
capacitance on temperature, voltage, frequency, and time. Used
in circuitry requiring very stable performance.
X7R:
Stable Class II dielectric, with predictable change in properties
across a temperature range of -55°C to +125°C. Used as
blocking, decoupling, bypassing, and frequency discriminating
elements. This dielectric is ferroelectric and provides higher
capacitance than Class I materials.
BX:
The military specification for ceramic chip capacitors (MIL-
PRF-55681) defines a mid-K stable dielectric designated as BX.
The BX specification has voltage temperature limits in addition
to temperature limits of capacitance. The BX dielectric is limited
to ±15% maximum change in capacitance between 25°C and
-55°C or +125°C and also has a voltage restriction of +15%
/ -25% maximum change in capacitance between 25°C and
-55°C or +125°C at rated voltage.
Z5U/Y5V:
General purpose Class III dielectrics with higher dielectric
constant and greater variation of properties over temperature
and voltage. Very high capacitance per volume is attainable
for general purpose applications where stability over a wide
temperature range is not critical.
