30 V to 60 V PTC Thermistors
For Overload Protection
FEATURES
• Wide range of trip and non-trip currents:
From 94 mA up to 2 A for the trip current
• Small ratio between trip and non-trip currents
(I
t
/I
nt
= 1.5 at 25 °C)
• High maximum overload current (up to 23 A)
• Leaded parts withstand mechanical stresses
and vibration
• UL file E148885 according to XGPU standard UL1434
• UL approved PTCs are guaranteed to withstand severe
test programs
• Long-life cycle tests (over 5000 trip cycles)
• Long-life storage tests (3000 h at 250 °C)
• Electrical cycle tests at low ambient temperatures
(- 40 °C or 0 °C)
• Damp-heat and water immersion tests
• Overvoltage tests at up to 200 % of rated voltage
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
Over-temperature/over-load protection:
• 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 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)
245 °C, duration: 5 s (Lead (Pb)-free)
Resistance to soldering heat
260 °C, duration: 10 s max.
MARKING
Only the grey lacquered thermistors with a diameter of
8.5 mm to 20.5 mm are marked with BC, R
25
value (example
1R9) on one side and I

, V
max.
on the other side.
