FlexiCapTM Termination

FlexiCapTM has been developed as a result of listening to

customer’s experiences of stress damage to MLCCs from many

manufacturers, often caused by variations in production

processes.

Our answer is a proprietary flexible epoxy polymer termination

material that is applied to the device under the usual nickel

barrier finish. FlexiCapTM will accommodate a greater degree of

board bending than conventional capacitors.

Ranges are available with FlexiCapTM termination material

offering increased reliability and superior mechanical

performance (board flex and temperature cycling) when

compared with standard termination materials. Refer to Syfer

application note reference AN0001. FlexiCapTM capacitors

enable the board to be bent almost twice as much as before

mechanical cracking occurs. Refer to application note AN0002.

FlexiCapTM is also suitable for space applications having passed

thermal vacuum outgassing tests. Refer to Syfer application

note reference AN0026.

Syfer has delivered millions of FlexiCapTM components and

during that time has collected substantial test and reliability

data, working in partnership with customers world wide, to

eliminate mechanical cracking.

An additional benefit of FlexiCapTM is that MLCCs can withstand

temperature cycling from -55 to 125˚C in excess of 1,000

times without cracking.

FlexiCapTM termination has no adverse effect on any electrical

parameters, nor affects the operation of the MLCC in any way.

Application Notes

FlexiCapTM may be handled, stored and transported in the

same manner as standard terminated capacitors. The

requirements for mounting and soldering FlexiCapTM are the

same as for standard SMD capacitors.

For customers currently using standard terminated capacitors

there should be requirement to change the assembly process

when converting to FlexiCapTM.

Based upon the board bend tests in accordance with IEC

60384-1 the amount of board bending required to

mechanically crack a FlexiCapTM terminated capacitor is

significantly increased compared with standard terminated

capacitors.

REACH (Registration, Evaluation, Authorisation and

restriction of Chemicals) Statement

The main purpose of REACH is to improve the protection of

human health and the environment from the risks arising from

the use of chemicals.

Syfer Technology Ltd maintains both ISO 14001,

Environmental Management System and OHSAS 18001 Health

& Safety Management System approvals that require and

ensure compliance with corresponding legislation such as

REACH.

For further information, please contact the sales office at

SyferSales@knowles.com

RoHS Compliance

Syfer routinely monitors world wide material restrictions (e.g.,

EU/China and Korea RoHS mandates) and is actively involved

in shaping future legislation.

All standard C0G/NPO, X7R, X5R and High Q Syfer MLCC

products are compliant with the EU RoHS directive (see below

for special exemptions) and those with plated terminations are

suitable for soldering common lead free solder alloys (refer to

‘Soldering Information’ for more details on soldering

limitations). Compliance with EU RoHS directive automatically

signifies compliance with some other legislation (e.g., Korea

RoHS). Please refer to the Sales Office for details of

compliance with other materials legislation.

Breakdown of material content, SGS analysis reports and tin

whisker test results are available on request.

Most Syfer MLCC components are available with non-RoHS

compliant tin/lead (SnPb) Solderable termination finish for

exempt applications and where pure tin is not acceptable.

Other tin free termination finishes may also be available –

please refer to the Sales Office for further details.

X8R ranges <250Vdc are not RoHS 2011/65/EU compliant.

115Vac 400Hz ranges are not RoHS 2011/65/EU compliant.

Check the website, www.knowlescapacitors.com/syfer for

latest RoHS update.

Export Controls and Dual-use Regulations

Certain Syfer catalogue components are defined as ‘dual-use’

items under international export controls – those that can be

used for civil and military purposes which meet certain

specified technical standards.

The defining criteria for a dual-use component with respect to

Syfer products is one with a voltage rating of >750V and a

capacitance value >250nF and a series inductance <10nH.

Components defined as ‘dual-use’ under the above criteria

automatically require a licence for export outside the EU, and

may require a licence for export with the EU.

The application for a licence is routine, but customers for these

products will be asked to supply further information.

Please refer to the sales office if you require any further

information on export restrictions.

Other special components may additionally need to comply

with export regulations.
