temperature coefficient and are primarily intended for
overload protection. They consist of a naked disk with two
tinned brass or copper clad steel leads and are coated with
a high temperature silicone UL 94 V-0 coating. Leadless
disks and leaded disks without coating are available on
request.
MOUNTING
The PTC Thermistors are suitable for processing on
automatic insertion equipment.

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.

Trip-time or switching time (t
s
)
To check the trip-time for a specific PTC, refer to the Electrical Data and Ordering Information tables for the value I
nt
. Divide the
overload or trip current by this I
nt
and you realize the factor I
t
/I
nt
. 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 I
t
/I
nt
factor and the switching time is a function of the PTC diameter; see the
above graphs.
