NTC SMD THERMISTORS NC 21 (AgPdPt Termination) Chip thermistors are high quality and low cost devices especially developed are suitable for hybrid assembly process (conductive adhesive), not suitable for surface mounting applications. They are widely used for temperature for lead free soldering. compensation but can also achieve temperature control of printed circuits. Its silver-palladium-platinum metallization provides a high degree of resistance to dewetting of the terminations (typically 260C / 15 s). Parts NC 21 Types IEC SIZE : 0603 DIMENSIONS: millimeters (inches) Terminations PdPtAg Marking On packaging only Climatic category 40/125/56 Operating temperature -55C to +150C * Tolerance on Rn (25C) 3% , 5%, 10%, 20% Maximum dissipation at 25C 0.07 W Thermal dissipation factor 1 mW/C Thermal time constant 4 s Resistance - Temperature characteristics: pages 29 to 33.
