Cautions and warnings  
General  
EPCOS thermistors are designed for specific applications and should not be used for purposes  
not identified in our specifications, application notes and data books unless otherwise agreed  
with EPCOS during the design-in-phase.  
Ensure suitability of thermistor through reliability testing during the design-in phase. The ther-  
mistors should be evaluated taking into consideration worst-case conditions.  
Storage  
Store thermistors only in original packaging. Do not open the package prior to processing.  
Storage conditions in original packaging: storage temperature 25 °C ... +45 °C, relative hu-  
midity 75% annual mean, maximum 95%, dew precipitation is inadmissible.  
Avoid contamination of thermistors surface during storage, handling and processing.  
Avoid storage of thermistor in harmful environment with effect on function on long-term opera-  
tion (examples given under operation precautions).  
Use thermistor within the following period after delivery:  
Through-hole devices (housed and leaded PTCs): 24 months  
Motor protection sensors, glass-encapsulated sensors and probe assemblies: 24 months  
Telecom pair and quattro protectors (TPP, TQP): 24 months  
Leadless PTC thermistors for pressure contacting: 12 months  
Leadless PTC thermistors for soldering: 6 months  
SMDs in EIA sizes 3225 and 4032, and for PTCs with metal tags: 24 months  
SMDs in EIA sizes 1210 and smaller: 12 months  
Handling  
PTCs must not be dropped. Chip-offs must not be caused during handling of PTCs.  
The ceramic and metallization of the components must not be touched with bare hands. Gloves  
are recommended.  
Avoid contamination of thermistor surface during handling.  
Soldering (where applicable)  
Use rosin-type flux or non-activated flux.  
Insufficient preheating may cause ceramic cracks.  
Rapid cooling by dipping in solvent is not recommended.  
Complete removal of flux is recommended.  
Standard PTC heaters are not suitable for soldering.  
Please read Cautions and warnings and  
Important notes at the end of this document.
