L Cautions & Warnings

General Release:

General:

All recommendations according to the general technical specifications of the data-sheet have to be complied with. Further the varistor is not designed

for voltage stabilization with continuous power dissipation.

The disposal and operation of the product within ambient conditions which probably alloy or harm the component surface has to be avoided.

The exposure of steam, saline spray, atmosphere with reduced oxygen content, corrosive gases, rain or condensation and direct sunlight shall be

prohibited.

If the product is potted in customer applications, the potting material might shrink and react chemically during and after hardening. According to this the

product is exposed to the pressure and material of the potting material with the effect that the ceramic body and termination is possibly damaged by

this pressure or the chemically reaction and so the electrical as well as the mechanical characteristics and the life time are in danger to be affected.

After the potting material is cured, the ceramic body and termination of the product have to be checked if any reduced electrical or mechanical

functions or destructions have occurred.

The responsibility for the applicability of customer specific products and use in a particular customer design is always within the authority of the

customer. All technical specifications for standard products do also apply for customer specific products.

Cleaning agents that are used to clean the application might damage or change the characteristics of the component, body, pins or termination and

might reduce the life time.

Direct mechanical impact to the product shall be prevented as the ceramic material of the ceramic body could flake or in the worst case it could break.

Signals operated continuously with a high ratio of direct-current voltage might have an influence on the product life time.

Product specific:

Follow all instructions mentioned in the datasheet, especially:

• The solder profile has to be complied with according to the technical reflow soldering specification, otherwise no warranty will be sustained.

• Wave soldering is only allowed after evaluation and approval.

• The compatibility of the SMT adhesive with the passivation layer of the component must be ensured

• All products shall be used before the end of the period of 12 months based on the product date-code, if not a 100% solderability can´t be warranted.

• Violation of the technical product specifications such as exceeding the nominal rated voltage will result in the loss of warranty.

The general and product specific cautions 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. Before incorporating this component into any equipment where higher safety and

reliability is especially required or if there is the possibility of direct damage or injury to human body, for example in the range of 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 must be

informed 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.
