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

• 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.

MOUNTING

The PTC Thermistors are suitable for processing on

automatic insertion equipment.

Soldering

< 240 °C; duration < 5 s

Resistance to heat

MARKING

Only the grey lacquered thermistors with a diameter of 8.5 to

20.5 mm are marked with BC, R25 value (example 1R9) on
