Storage of PTC thermistors
PTC thermistors should be soldered after shipment from EPCOS within the time specified:
Use thermistor within the following period after delivery:
Through-hole devices (housed and leaded PTCs)
Motor protection sensors, glass-encapsulated sensors and probe assemblies
Telecom pair and quattro protectors (TPP, TQP)
Leadless PTC thermistors for pressure contacting
Leadless PTC thermistors for soldering
SMDs in EIA sizes 3225 and 4032, and for PTCs with metal tags
SMDs in EIA sizes 0402, 0603, 0805 and 1210

The parts are to be left in the original packing.
Storage temperature:
Relative humidity:
25 ... + 45 °C
≤ 75% annual average, ≤ 95% on 30 days in a year
The solderability of the external electrodes may be deteriorated if SMDs are stored where they
are exposed to high humidity, dust or harmful gas (hydrogen chloride, sulfuric acid gas or hydro-
gen sulfide).
