Data Sheet

The following conditions apply to all goods within the product series of Super
Capacitors of Würth Elektronik eiSos GmbH & Co. KG:
General:
• This electronic component was designed and manufactured for use in general electronic equipment.
• Würth Elektronik must be asked for a written approval (following the certain PPAP level procedure) before incorporating the components
into any equipment in the field such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train
control, ship control), transportation signal, disaster prevention, medical, public information network etc. where higher safety and
reliability are especially required and/or if there is the possibility of direct damage or human injury.
• Electronic components that will be used in safety-critical or high-reliability applications, should be pre-evaluated by the customer.
• Direct mechanical impact to the product shall be prevented as material of the body, pins or termination could flake or in the worst case
it could break.
• Avoid any water or heavy dust on capacitors surface, which may cause electrical leakage, damage, overheating or corrosion.
• Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth
Elektronik does not guarantee any customer qualified product characteristic, beyond Würth Elektronik specifications, for its validity and
sustainability over time.
• The customer is responsible for the functionality of their own products. All technical specifications for standard products also apply to
customer specific products.
• The component was designed and manufactured to be used within the datasheet specified values. If the usage and operation conditions
specified in the datasheet are not met, the body, pins or termination may be damaged or dissolved.
• Do not apply any kind of flexural or compressive force onto soldered or unsoldered component.
• The capacitance tolerance as specified within the datasheet is only valid on the date of delivery and according specified measurement
criteria.
Product specific:
Polarity:
The product has a polarity. In operation this polarity needs to be considered and adhered. Reverse voltage can damage or destroy the
product. The polarity is marked with a stripe and the word NEG as well as a negative sign on the lateral surface of the capacitor.
Overvoltage:
Avoid any overvoltage and do not apply a continuous overvoltage. If an overvoltage is applied to the capacitor, the leakage current can
increase drastically. The applied working voltage is not allowed to exceed the rated working voltage of the specific capacitor.
Operating Temperature:
The capacitor shall not be operated above the operating temperature, which is stated within this datasheet of the specific capacitor. The
achievable lifetime of the capacitor is correlating to the applied temperature. In order to achieve the maximum lifetime, the capacitor should
be operated by the lowest possible temperature conditions within the application. During charging and discharging in a short cycles, self-
heating is generated by internal resistance. The operating temperature should not exceed the above stated operating temperature, including
any self-heating.
Charge and Discharge:
Frequent and quick charge / discharge cycles may generate heat inside the capacitor. Do not exceed the above stated discharge current.
Exceeding the maximal current, stated above, can cause a decrease of capacitance, an increase of leakage current or breakdown. For
assistance with your application please consult our technical support.
Storage Conditions:
The storage conditions for a capacitor are recommended to be as given above. Do not expose the capacitor to environments with hazardous
gas, ozone, ultraviolet rays or any kind of radiation. Avoid any contact of the capacitor with direct sunshine, saltwater, spray of water or types
of oil during storage. All products shall be used before the end of the period of 24 months based on the product date code, if not a 100 %
solderability cannot be guaranteed. The capacitance tolerance as specified within the datasheet is only valid on the date of delivery.
Soldering:
The solder profile must comply with the Würth Elektronik technical soldering specification. All other profiles will void the warranty.All other
soldering methods are at the customers’ own risk.Strong forces which may affect the coplanarity of the components’ electrical connection
with the PCB (i.e. pins), can damage the part, resulting in avoid of the warranty.Do not use excessive nor insufficient flux.Provide enough
washing when water-soluble flux is used.During wave soldering only the pins / terminals should have contact with hot solder bath / wave.
Assure that no direct contact of capacitor body with hot solder bath / wave or any other component will happen. Soldering must be done
from the opposite PCB side where capacitor body is placed.
Dangerous Goods and Handling:
Due to the European agreement concerning the international carriage of dangerous good by road (ADR) capacitors with an energy storage
capacity of 0.3 Wh or more are considered as dangerous goods. Refer to special provision 361 for detailed information. Each capacitor
should be protected against unintended short circuit or be fitted with a metal strap connecting the terminals, if transported. Capacitors
installed in equipment shall be either in an uncharged state or protected against short circuit. A fully charged capacitor shall not be short
circuited without a protective resistor of at least 1 kΩ.
Cleaning:
Do not wash the assembled capacitors with the following cleaning agents:

This electronic component has been designed and developed for usage in general electronic equipment only. This product is not authorized for use in equipment where a higher safety standard and reliability standard is especially required or where a failure of the product is reasonably expected to cause severe personal injury or death, unless the parties have executed an agreement specifically governing such use. Moreover Würth Elektronik eiSos GmbH
& Co KG products are neither designed nor intended for use in areas such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc.. Würth Elektronik eiSos GmbH & Co KG must be informed about the intent of such usage before the design-in stage. In addition, sufficient reliability evaluation checks for safety
must be performed on every electronic component which is used in electrical circuits that require high safety and reliability functions or performance.
