Cautions and warnings
Storage
Store thermistors only in original packaging. Do not open the package before storage.
Storage conditions in original packaging: storage temperature -25°C ...+45°C, relative humidity ≤ 75%
annual mean, maximum 95%, dew precipitation is inadmissible.
Do not store SMDs where they are exposed to heat or direct sunlight. Otherwise, the packing material may
be deformed or SMDs may stick together, causing problems during mounting.
Avoid contamination of thermistors surface during storage, handling and
processing.
Avoid storage of thermistor in harmful environments like corrosive gases (SOx, Cl etc.)
After opening the factory seals, such as polyvinyl-sealed packages, use the SMDs as soon as possible.
Solder thermistors after shipment from EPCOS within the time specified:
SMD with nickel barrier termination: 12 months
SMD with AgPd termination: 6 months
Handling
NTC thermistors must not be dropped. Chip-offs must not be caused during handling of NTCs.
Components must not be touched with bare hands.
Gloves are recommended.
Avoid contamination of thermistor surface during handling.
Soldering
Use resin-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.
