Chip thermistors are high quality and low cost devices

especially developed for surface mounting applications. They

are widely used for temperature compensation but can also

achieve temperature control of printed circuits.

A nickel barrier metallization provides outstanding qualities of

solderability and enables this chip to meet the requirements

of the most severe soldering processes.

APPLICATIONS

• LCD compensation

• Battery packs

• Mobile phones

• CD players

• Heating systems

• Air-conditioning systems

• Temperature control of Switch Mode Power Supplies

• Compensation of pressure sensors

• Protection of power transistors in various electronic circuits
