FEATURES

• Wide range of trip and non-trip currents:

• Small ratio between trip and non-trip currents

• High maximum overload current (up to 23 A)

• Leaded parts withstand mechanical stresses

• UL file E148885 according to XGPU standard UL1434

• UL approved PTCs are guaranteed to withstand severe

• Compliant to RoHS directive 2002/95/EC and in

APPLICATIONS

Over-temperature/over-load protection:

• Telecommunications

• Automotive systems

• Industrial electronics

• Consumer electronics

• Electronic data processing

DESCRIPTION

These

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

1R9) on one side and I

From 94 mA up to 2 A for the trip current

and vibration

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

• Damp-heat and water immersion tests

• Overvoltage tests at up to 200 % of rated voltage

accordance to WEEE 2002/96/EC
