Important notes at the end of this document.

 Specified values only apply to CTVS components that have not been subject to prior electrical,

mechanical or thermal damage. The use of CTVS devices in line-to-ground applications is

therefore not advisable, and it is only allowed together with safety countermeasures like

thermal fuses.

Storage



Only store CTVS in their original packaging. Do not open the package before storage.



Storage conditions in original packaging: temperature −25 to +45°C, relative humidity ≤75%

annual average, maximum 95%, dew precipitation is inadmissible.



Do not store CTVS devices where they are exposed to heat or direct sunlight. Otherwise the

packaging material may be deformed or CTVS may stick together, causing problems during

mounting.



Avoid contamination of the CTVS surface during storage, handling and processing.



Avoid storing CTVS devices in harmful environments where they are exposed to corrosive



Use CTVS as soon as possible after opening factory seals such as polyvinyl-sealed packages.



Solder CTVS components after shipment from EPCOS within the time specified:

o

CTVS with Ni barrier termination, 12 months

o

CTVS with AgPd termination, 6 months

o

SHCV and CU series, 24 months

Handling



Do not drop CTVS components and allow them to be chipped.



Do not touch CTVS with your bare hands - gloves are recommended.



Avoid contamination of the CTVS surface during handling.

Mounting



When CTVS devices are encapsulated with sealing material or overmolded with plastic

material, be sure to observe the precautions in “Mounting instructions”, “Sealing, potting and

overmolding”.



Make sure an electrode is not scratched before, during or after the mounting process.



Make sure contacts and housings used for assembly with CTVS components are clean before

mounting.
