General Information

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.

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.

NO OBSOLESCENCE

Choosing a standard or custom EXXELIA product means you won’t have to wor-

ry about obsolescence.

TYPICAL APPLICATIONS

• Aerospace & Defense: cockpit panels, flight control, radio systems, missile

guidance systems…

• Space: military and commercial satellites, launcher…

• Medical: MRI, external defibrillators, implantable devices…

• Telecommunications: base stations…

• Oil and gas: drilling tools, MWD, LWD, wellheads…

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».

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 mecha-

nism for the mineral procurement chain, encouraging importers to buy only

«certified» ore.

We have discontinued relations with suppliers that procure from the Demo-

cratic Republic of the Congo or an adjoining country.

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.

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).

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 re-

quest, the coating is pure silver.
