30 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
• Wide range of resistance: from 0.3 Ω up to 50 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 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 hours 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
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
• 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 disc with two
tinned brass or copper clad steel leads and coated. Leadless
disks and leaded disks without coating are available on
request.
