APPLICATIONS
Overload (current, voltage, temperature) protection in:
• Telecommunications
• Industrial electronics
• Consumer electronics
• Electronic data processing
DESCRIPTION
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.
MARKING
Only the grey lacquered thermistors with a diameter of
8.5 mm to 20.5 mm are marked with BC, R25 value (example
1R9) on one side and Int, Vmax. on the other side.
