Application Specific MLCs
Problem Solving at the Leading Edge
As the world’s leading manufacturer and innovator in
application specific multilayer ceramic (ASMLC) capacitors,
AVX offers a unique technological and production capability
to the field. AVX actively pursues and satisfies the high
reliability and custom needs of a variety of governmental
and industrial customers. Successful involvement in
missile programs, extensive work in ultra-high reliability
telecommunications and sophisticated capacitor design
applications – all have established AVX as the source for
advanced and high reliability ASMLC capacitors.
Advanced
Products are ISO9001 certified organizations for design
and manufacturing of MLC capacitors.
AVX Advanced Application Capacitors are organized around
three distinct functions:
• Application Specific Development Laboratories
• Advanced Manufacturing Facilities
• Quality Control

Problem Solving at the Leading Edge
APPLICATION SPECIFIC
DEVELOPMENT LABORATORIES
Initially, AVX technical personnel communicate with customers
to learn the requirements that the new capacitor must satisfy.
The personnel involved are well-versed in material, manufac-
turing and electronic application technologies. They study the
overall application and the environment in which the part will
function. Programs are begun for selection of appropriate
ceramic formulations, metal systems and designs. These pro-
grams yield a detailed technology profile from which mechan-
ical design and process specifications follow.
requirements. This includes special lead configurations and
multiple chip packaging that simplifies the mounting of
specialty capacitors. To the customer, the total capability of
AVX assures a high level of consistent control at all steps of
production.
QUALITY CONTROL
The Q. A. organization is an integral part of manufacturing.
Quality Control tests the product of each manufacturing
process, detects flaws or variations from the narrow
acceptable standard and isolates the cause of the deviation.
Corrective action can then be taken to return the process to
within its predetermined control levels.
Quality Assurance has large and well-equipped laboratories
where statistical samples are evaluated and tested to
determine failure rates, characterize products and assure
compliance with specification. Both destructive and non-
destructive testing are used, including advanced ultrasonic
inspection equipment for non-destructive inspection of an
entire production quantity.
Put the experience, technology and facilities of the leading
company in multilayer ceramics to work for you. No other
source offers the unique combination of capability and
commitment to advanced application specific components.
ADVANCED
MANUFACTURING FACILITIES
The ability and reputation of AVX in high reliability MLCs is due
in part to the company’s complete control over all phases of
the production process. This includes powder processing,
tape casting and/or wet build-up, green MLC assembly and
final capacitor assembly/packaging. Recent renovations at
AVX have upgraded green MLC assembly areas to certified
clean room levels.
A favorite feature with many customers of AVX is our ability
to work with customers in solving special packaging

SMPS Capacitors
SMPS Capacitor Applications
FOREWORD
High speed switch mode power supplies place high
demands on the capacitors used in the input or output filters
of Resonant DC-DC or Pulse Modulated DC-DC converters.
AVX Corporation has developed several multilayer ceramic
(MLC) capacitor styles for these switcher applications. These
capacitors have been extensively tested and characterized
and found to have almost ideal performances to meet the
stringent requirements of these applications.
Output Filter Capacitor
The output from the switching circuit of a Switcher consists
of current on and off. From an elevated DC reference, this
current is an AC ripple additive on the DC. In order to smooth
this ripple effect, a filter circuit (usually inductive input) is built
to allow a storage of energy to take place during the rising
ripple portion and to allow a discharge of energy during the
falling ripple portion.
The ESR and ESL of the capacitor contribute to the net ripple
effect. The output filter capacitor is chosen for ESR, and with
previous types of capacitors, multiples were used in an
attempt to lower the net ESR. The MLC offers ESRs well
below the minimum allowable to lower noise levels, thus
eliminating the need for multiple units.
Input Filter Capacitor
The Input Filter capacitor is required to perform two functions:
To supply an unrestricted burst of current to the power supply
switch circuitry and to not only do it without generating any
noise, but to help suppress noise generated in the switch
circuitry. It is, in effect, a very large decoupling capacitor. It
must have very low ESL, capabilities for very high dv/dt, as
well as di/dt and it must have a very low ESR to eliminate
power loss.
The distance from the primary DC source, as well as the type
of capacitor used in this source (usually electrolytics),
presents a very high inductance to the input of the Switcher.
The MLC input capacitor, with its excellent ESL and ESR
characteristics, is located physically close to the switch
circuitry. Repetitive peak currents, inherent with the Switcher
design, require a high ripple capability, as well as high surge
capability for transients, both induced and conducted from
other sources. MLCs have both these capabilities.

SMPS Applications
AVX also manufactures coupling, decoupling, resonant and
snubber capacitors for SMPS applications. Contact AVX for
