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.

Vishay BCcomponents 145 V PTC Thermistors

VOLTAGE DERATING AS A FUNCTION OF AMBIENT TEMPERATURE
ELECTRICAL CHARACTERISTICS Imax. AS A FUNCTION OF VOLTAGE
Imax. 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 Imax. 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.
TYPICAL TRIP-TIME AS A FUNCTION OF TRIP CURRENT RATIO
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 = 0 °C of a thermistor type 2381 661 52112; 12 Ω; Ø Dmax. =7.0mm:
Int from the table: 210 mA at 25 °C
Int: 210 x 1.12 = 235 mA (at 0 °C).
Overload current = 0.8 A; factor It/Int: 0.8/0.235 = 3.40. In the typical trip-time as a function of trip current ratio graph, at the 7.0 mm
line and It/Int = 3.40, the typical trip-time is 6.0 s.
