DESCRIPTION
These directly heated thermistors have a positive
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.
Typical soldering
235 °C; duration: 5 s (Pb-bearing)

MARKING
Only the grey lacquered thermistors with a diameter of
8.5 mm to 20.5 mm are marked with BC, R

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 I
overload or trip current by this I
and you realize the factor It/Int. This rule is valid for any ambient temperature between 0 °C
nt
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.
