These directly heated ceramic-based thermistors have a
positive temperature coefficient and are primarily intended
for overload protection. They consist of a ceramic pellet
soldered between two tinned CCS wires and coated with a
UL 94 V-0 high temperature hard silicone lacquer.
MOUNTING
PTC thermistors can be mounted by wave, reflow, or
hand-soldering. Current levels have been determined
according IEC 60738 conditions. Different ways of
mounting or connecting the thermistors can influence their
thermal and electrical behavior. Standard operation is in still
air, any potting or encapsulation of PTC thermistors is not
recommended and will change its operating characteristics.
Typical Soldering
235 °C; duration: 5 s (Lead (Pb)-bearing)
245 °C, duration: 5 s (Lead (Pb)-free)
Resistance to Soldering Heat
260 °C, duration: 10 s max.
QUALITY
UL approved PTCs are guaranteed to withstand severe test
programs and have factory audited follow-up programs.
Major UL qualification tests are long-life (6000 cycles)
electrical cycle tests at trip-current, long-life stability
storage tests (3000 h at 250 °C), damp heat and water
immersion tests and over-voltage tests up to 200 % of rated
voltage.
UL approved PTCs are guaranteed to withstand severe test
programs
• Long-life cycle tests (over 5000 trip cycles)
• Long-life storage tests (3000 h at 250 °C)
• Electrical cycle tests at low ambient temperatures
(-40 °C or 0 °C)
• Damp-heat and water immersion tests
• Overvoltage tests at up to 200 % of rated voltage
MARKING
Only the gray lacquered thermistors with a diameter of
8.5 mm to 20.5 mm are marked with BC,
