265 V PTC Thermistors For

Overload Protection

FEATURES

• Wide range of trip and non-trip currents: from 11 mA up to

800 mA for the trip current

• Wide range of resistance: from 2.1 Ω up to 3 KΩ

• 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 withstande severe

test programmes

• 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

APPLICATIONS

• Telecommunications

• Automotive systems

• Industrial electronics

• Consumer electronics

• Electronic data processing.

DESCRIPTION

These directly heated thermistors have

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.
