ISO 9001:2008 Certification

ISO 9001:2008 is an international basic 
standard of quality assurance systems for all 
branches of industry. The approval 
according to ISO 9001:2008 of our 
factories by the VDE inspectorate certifies 
that organisation, equipment and moni-
toring of quality assurance in our factories
correspond to internationally recognized 
standards.

WIMA WPCS

The  WIMA Process Control System (WPCS)
is a quality surveillance and optimization 
system developed by WIMA. WPCS is a 
major part of the quality-oriented WIMA 
production. Points of application of WPCS
during production process:

 

Incoming material inspection

 

Metallization

 

Film inspection

 

Schoopage

 

Pre-healing

 

Lead attachment

  

Cast resin preparation/encapsulation

 

100% final inspection

 

AQL check

WIMA Environmental Policy

All WIMA capacitors, irrespective of whether 
through-hole devices or SMD, are made of 
environmentally friendly materials. Neither 
during manufacture nor in the product itself 
any toxic substances are used, e.g.

- Lead

- PBB/PBDE

- PCB

- Arsenic

- CFC

- Cadmium

- Hydrocarbon chlorid - Mercury
- Chromium 6+

- etc.

We merely use pure, recyclable materials for 
packing our components, such as:
 

 carton
 cardboard

conditions, the temperature inside the 
component may rise to an impermissibly 
high level. Thus, the dielectric film may 
subsequently be damaged leading to a short 
circuit or formation of smoke and even fire 
in the capacitor. It may also happen if the 
capacitor is overheated by an external heat 
source.

Shock and/or Vibration Load for 
Larger Case Sizes

For increased shock and vibration 
applications involving larger case sizes (i.e., 
PCM 22.5 mm lead spacing or greater), it is 
recommended to fix capacitors in an 
appropriate way; or special lead and tab 
terminations may be required respectively, to 
minimize lead separation from the capacitor 
element or the solder joint.

Processing

When processing plastic film capacitors it is 
mandatory to observe the application 
recommendations with regard to soldering 
and/or cleaning and drying processes.

General Remarks

All data, range surveys and application data 
correspond to the actual state of the art and 
were elaborated as thoroughly and precisely 
as possible. They are to be understood as 
general information, and the right for 
amendments and construction changes is 
reserved. Special customized designs which 
deviate from our catalogue data, 
irrespective of whether being based on 
factory standards, specifications or related 
data, do not release the user from his duty 
of care with regard to incoming goods 
inspection and production monitoring. In 
case of the components being purchased 
through second or third suppliers we 
urgently ask to compare the technical details 
with the data given by the manufacturer. In 
cases of doubt we recommend use is made 
of our technical support, since we do not 
take any responsibility for damages caused 
by inappropriate use or processing of our 
capacitors.

RoHS Compliance

According to the RoHS Directive 
2011/65/EC certain hazardous substances 
like e.g. lead, cadmium, mercury must not 
be used any longer in electronic equipment 
as of July 1st, 2006. For the sake of the 
environment WIMA has refraind from using 
such substances since years already.

Tape for lead-free WIMA capacitors

DIN EN ISO 14001:2009

WIMA’s environmental management has 
been established in accordance with the 
guidelines of DIN EN ISO 14001:2009 to 
save energy and resources.

AC Voltage Load at the Mains

Anticipating possible interfering pulses, DC 
voltage capacitors must not be operated at 
the mains (line power), irrespective of the 
rated AC voltage. For this purpose, use 
approved electromagnetic interference 
suppression capacitors only.

Thermal Load in the Application

If a plastic film capacitor is overstressed due 
to inappropriate usage under AC voltage
