265 V PTC Thermistors

For Overload Protection

FEATURES

• Wide range of trip and non-trip currents:

From 11 mA up to 800 mA

• Small ratio between trip and non-trip currents

= 1.5 at 25 °C)

• High maximum inrush current (up to 5.5 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 metallized ceramic

disk with two tinned brass or copper clad steel leads reflow

soldered to it and coated with a high temperature silicone

lacquer. 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

value (example

1R9) on one side and I

, V

max.

on the other side.
