MATERIALS EXPERT
For 50 years and as a market leader, EXXELIA’s comprehensive knowledge of
the materials properties and performances have enabled us to design capaci-
tors in Porcelain, NPO, BX, 2C1, BP, X7R and -2200ppm/° C ceramics.
ENVIRONMENT
EXXELIA is committed to applying a robust environmental policy, from product
design through to shipment. To control its environmental footprint and recon-
cile this with the company’ functional imperatives, our environmental policy
provides for the reduction or elimination of hazardous substances. We also
focus on compliance with European Union directives and regulations, notably
REACH and RoHS.
CUSTOM DESIGNS
Our catalog products don’t meet your application?
Based on the valuable experience accumulated over the design of 2,000+ spe-
cific ceramic capacitors, you can trust EXXELIA to define a qualitative custom
solution in a time effective manner.
RoHS COMPLIANCY
SMD CAPACITORS
The capacitor terminations are generally protected by a nickel barrier formed
by electrolytic deposit. This barrier gives chip capacitors leaching performance
far exceeding the requirements of all applicable standards. The nickel barrier
guarantees a minimum resistance to soldering heat for a period of 1 minute at
260°C in a tin-lead (60/40) or tin-lead-silver (62/36/2) bath without noticeable
alteration to the solderability. It also allows repeated soldering-unsoldering
and the longer soldering times required by reflow techniques.
However nickel barrier amplifies thermal shock and is not recommended for
chip sizes equal or greater than CNC Y (30 30) - (C 282 to C 288 - CNC 80 to
CNC 94).

NO OBSOLESCENCE
Choosing a standard or custom Exxelia product means you won’t have to worry
about obsolescence.
TYPICAL APPLICATIONS
• Aerospace & Defense: cockpit panels, flight control, radio systems, missile
guidance systems…

ISO 9001 AND AS9100C
Quality is at the core of Exxelia’s corporate culture. Each sites has its own cer-
tifications.
CERTIFICATIONS
Capacitors manufactured by EXXELIA comply with American and European
standards and meet the requirements of many international standards.
For Space qualified parts (ESA QPL), please refer to our catalog «Ceramic ca-
pacitors for Space applications».
LEADED COMPONENTS
As well as for SMD products, leaded capacitors ranges can also be RoHS. These
products, which are characterized by the suffix «W» added to the commercial
type, are naturally compatible with the soldering alloys used in RoHS mounting
technology. The connections coating is generally an alloy SnAg (with a maxi-
mum of 4% Ag). However, on a few products that Exxelia will precise on request,
the coating is pure silver.
QUALITY & RELIABILITY
EXXELIA is committed to design and manufacture high quality and reliability
products. The test cycles reproducing the most adverse operating conditions
over extended periods (up to 10 000 hours) have logged to date well over
5.109 hours/°Component.
Failure rate data can be provided upon request.
CONFLICT MINERALS
EXXELIA is committed to an approach based on «Conflict Minerals Compli-
ance». This US SEC rule demands complete traceability and a control mech-
anism for the mineral procurement chain, encouraging importers to buy only
«certified» ore.
We have discontinued relations with suppliers that procure from the Democrat-
ic Republic of the Congo or an adjoining country.
