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
gases for example (SO
x
, Cl).
•
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.
