Datasheet

Cautions and Warnings:
The following conditions apply to all goods within the product series of WE-CLFS 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 written approval (following the PPAP procedure) before incorporating the components into any
equipment in fields 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.
• 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 wire insulation may be damaged or dissolved.
• Do not drop or impact the components, as the core may flake apart.
• 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 characteristics beyond Würth Elektroniks’ 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.
Product specific:
Assembly instructions:
• While mounting and removing, the electronic component shall be operated in voltage-free condition pursuant to the five safety rules
described in the standard EN 50110-1.
• The protective earth connection shall be the first to be connected while installing the filter and shall be the last to be disconnected. The
protective earth connection must be prepared considering the leakage current.
• The filter position is suggested to be close as possible to the application. If there are long distances between the filter and application, it
is recommended to shield the cables, otherwise, the functionality might be affected.
• To establish a low impedance path for parasitic currents the filter housing shall have a wide connection area to the ground plane. The
ground plane shall be free of paint or other isolating materials.
• Keep the connection to the PE as short as possible.
• To minimize crosstalk do not place incoming and outgoing cables next to each other.
• Use short cables to minimize the parasitic effects of the setup.
• The connection to the ground plane should be established with M4 screws. The tightening torque varies with the selected screw and
should not exceed the limit of 5Nm.
Cleaning and Washing:
• Washing agents used during the production to clean the customer application might damage or change the characteristics of the
component. Washing agent may have a negative effect on the long-term functionality of the product.
Storage Conditions:
• A storage of Würth Electronik products for longer than 12 months is not recommended. Within other effects, the terminals may suffer
degradation, resulting in bad solderability. Therefore, all products shall be used within the period of 12 months based on the day of
shipment.
• Do not expose the components to direct sunlight.
• The storage conditions in the original packaging are defined according to DIN EN 61760-2.
Handling:
• Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.
• Only qualified personnel should work with the electronic component including, but not limited to, work such as planning, assembly,
installation, operation, repair and maintenance considering the corresponding documentation.
• The filter includes components storing an electric charge and dangerous voltage may remain at the filter terminals even after the power
source has been disconnected even after five minutes.
• In case temporary voltage is applied to the unassembled filter, the filter shall be discharged after the power source has been
disconnected.
• Avoid any overload or conditions that are not specified in the datasheet.
• Do not exceed the specified temperature limits.
• To maintain regular operation, the filters shall be protected within the application against inadmissible exceedance of the rated current.
• The filter leakage current specified in the data sheet merely serves as a user information. For security reasons, the maximum leakage
current of the entire electrical application has to be limited. The permissible limits for your application must be acquired from the relative
and applicable regulations, provisions and standards.
• The current derating must be observed. Disregarding the current derating might result in overheating and in a fire hazard as a
consequence thereof.
• Due to the heavy weight of the electronic component, strong forces and high accelerations might have the effect to damage the
electrical connection and will void the warranty.
Vibration resistance:
• Do not exceed the vibration limits given by IEC60068-2-6.
These cautions and warnings comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable.
However, no responsibility is assumed for inaccuracies or incompleteness.

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.
