 The surface temperature of an operating CTVS can be higher. Ensure that adjacent
components are placed at a sufficient distance from a CTVS to allow proper cooling.
 Avoid contamination of the CTVS surface during processing.
 Multilayer varistors (MLVs) with AgPd termination are not approved for lead-free soldering.
Soldering
 Complete removal of flux is recommended to avoid surface contamination that can result in an
instable and/or high leakage current.
 Use resin-type or non-activated flux.
 Bear in mind that insufficient preheating may cause ceramic cracks.
 Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack.
Conductive adhesive gluing
 Only multilayer varistors (MLVs) with an AgPd termination are approved for conductive
adhesive gluing.
Operation
 Use CTVS only within the specified operating temperature range.
 Use CTVS only within specified voltage and current ranges.
 Environmental conditions must not harm a CTVS. Only use them in normal atmospheric
conditions. Reducing the atmosphere (e.g. hydrogen or nitrogen atmosphere) is prohibited.
 Prevent a CTVS from contacting liquids and solvents. Make sure that no water enters a CTVS
(e.g. through plug terminals).
 Avoid dewing and condensation.
 EPCOS CTVS components are mainly designed for encased applications. Under all
circumstances avoid exposure to:
o direct sunlight
o rain or condensation
o steam, saline spray
o corrosive gases
o atmosphere with reduced oxygen content
