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
FEATURES
• Wide range of trip and non-trip currents:
From 11 mA up to 800 mA
• Small ratio between trip and non-trip currents
(It/Int = 1.5 at 25 °C)
• High maximum inrush current (up to 5.5 A)
• Leaded parts withstand mechanical stresses
and vibration
• UL file E148885 according to XGPU standard UL1434
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
Overload (current, voltage, temperature) protection in:
• 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 gray 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.

Vrated (%)
Iol max. as stated in the electrical data and ordering information tables, is the maximum overload current that may flow through
the PTC when passing from the low ohmic to high ohmic state at rated voltage.
When other voltages are present after tripping, the Iol max. value can be derived from the above Imax. as a function of voltage
graph. Voltages below Vrated will allow higher overload currents to pass the PTC.

Trip-Time or Switching Time (ts)
To check the trip-time for a specific PTC, refer to the Electrical Data and Ordering Information tables for the value Int. Divide the
overload or trip current by this Int and you realize the factor It/Int. This rule is valid for any ambient temperature between 0 °C
and 70 °C. Adapt the correct non-trip current with the appropriate curve in the Current Deviation as a Function of the Ambient
Temperature graph. The relationship between the It/Int factor and the switching time is a function of the PTC diameter; see the
above graphs.
Example
What will be the trip-time at Iol = 0.8 A and Tamb = 50 °C of a thermistor type PTCCL09H171HBE; 22 Ω; Ø Dmax. = 8.5 mm:
Int from the table: 170 mA at 25 °C
Int: 170 x 0.87 = 148 mA (at 50 °C)
Overload current = 0.8 A; factor It/Int: 0.8/0.148 = 5.40. In the Typical trip-time as a function of trip current ratio graph, at the
8.5 mm line and It/Int = 5.40, the typical trip-time is 3.0 s.
