Store thermistors only in original packaging. Do not open the package before storage.
Storage conditions in original packaging: storage temperature
humidity 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 environments like corrosive gases (SO
Solder thermistors after shipment from EPCOS within the time specified:
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.
In case of exposure of the NTC thermistors to water, electrolytes or other aggressive media,
these media can penetrate the coating and reach the surface of the ceramic. Low-ohmic or
high-ohmic behavior may occur due to the formation of an electrolyte with metals (silver/lead/tin
from metallization or solder). Low-ohmic behavior is caused by electrochemical migration,
high-ohmic behavior by dissolving of the electrode. Ineither case, the functionality of the NTC
thermistors can not be assured.
A lead (wire) may be bent at a minimum distance of twice the wire’s diameter plus 4 mm from
the component head or housing. When bending ensure the wire is mechanically relieved at the
component head or housing. The bending radius should be at least 0.75 mm.
Twisting (torsion) by 180 of a lead bent by 90 is permissible at 6 mm from the bottom of the
thermistor body.
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.
Leaded components: 24 months
