PTC Thermistors For Overload
And Overcurrent Protection
FEATURES
•
Different voltages to be chosen in function of the
application
•
Available in three mechanical versions:
– 2322 66. 4.... naked discs
– 2322 66. 5.... leaded and coated
– 2322 66. 6.... taped, on reel (to diameter 12.5 mm)
•
Wide range of trip and non-trip currents: from 17 mA up to
4.5 A for the trip current
•
Wide range of resistance: from 0.3
Ω
up to 3 k
Ω
•
Small ratio between trip and non-trip currents
(I
t
/I
nt
= 1.5 at 25
°
C)
•
High maximum inrush current
•
Excellent long term behaviour, also in humidity
•
Leaded parts withstand mechanical stresses and vibration
•
UL approved PTCs are guaranteed to withstand severe
test programmes including:

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 or copper clad steel leads and coated.
PACKAGING
All tape and reel specifications are in accordance with
“IEC
60286-3”
.

Notes
1. The thermistors are clamped at the seating plane.
2. For leadless types the values given for I
nt
and I
t
are only valid for thermistors mounted in accordance with
“IEC 60738”
. Thermistor dissipation
depends on mounting and can slightly affect the typical values.
3. For leadless types replace the 8
th
digit in the catalog numbers by 4.
4. I
max
is the maximum overload current that may flow through the PTC when it passes from the low ohmic to the high ohmic state.

I
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 I
max
value can be derived from the above I
max
as a function of voltage graph.
Voltages below V
rated
will allow higher overload currents to pass the ptc.
Example
What maximum overload current is allowed for a thermistor type 2322 662 52513 at 0
°C
and a maximum voltage after tripping
of 180 V
RMS
:
I
max
at 230 V and 25
°C
= 1.5 A
RMS
: see electrical data and ordering information for 2322 66. 4/5/6...3; max. voltage = 265 V
(ac or dc) table.
I
max
at 180 V and 25
°C
= 1.85 A
RMS
(180 V
RMS
= 78% of 230 V
RMS
gives 123% of I
max
).
At 0
°C
this gives 1.68 A
RMS
maximum overload current. See Current deviation as a function of the ambient temperature drawing.
