FEATURES
Different voltages to be chosen in
function of the application
Available in three mechanical
versions
2322 66. 0.... naked discs
2322 66. 1.... leaded
2322 66. 3.... taped, on reel
(to diameter 12.5 mm)
Wide range of trip and non-trip
currents: from 17 mA up to 3 A for
the trip current
Wide range of resistance: from
1.6 up to 1.9 k
Small ratio between trip and
non-trip currents
(It/Int 1.5 at 25 °C)
Leaded parts withstand mechanical
stresses and vibration.
APPLICATIONS
Telecommunications
Automotive systems
Industrial electronics
Consumer electronics
Electronic data processing.
DESCRIPTION
These directly heated thermistors
have a positive temperature
coefficient and are primarily intended
for overload protection. They consist
of a naked disc or with two tinned
brass leads.

Trip-time or switching time (ts)
To check the trip-time for a specific PTC, refer to Table 3 or 4 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 and 70 °C. Adapt the correct
non-trip current with the appropriate curve in Fig.6. Figure 7 shows the relationship between the It/Int factor and the
switching time as a function of the PTC diameter.
EXAMPLE
What will be the trip-time at Iol = 3 A and Tamb =10°C of a thermistor type 2322 662 12711; 6.5 ;D = 12 mm:
Int from Table 3: 350 mA at 25 °C
Int: 350 ×1.08 = 378 mA (10 °C).
Overload current = 3 A; factor: 30.378 = 7.94. In Fig.7 at the 12 mm line and It/Int = 7.94, the typical trip time is 1.6 s.
Fig.8 Typical trip time as a function of trip current ratio for 2322 66. 0/1/3...3 and 2322 66. 0/1/3...1 (D > 12 mm).

Curve 4: D = 10.0 mm.
