Datasheet
## **NTC SMD Thermistors** ## **NC 12 – NC 20** Chip thermistors are a high quality and low cost device especially developed for surface mounting applications. They are widely used for temperature compensation but can also (typically 260°C / 30 s). achieve temperature control of printed circuits. Its silver - palladium - platinum metallization provides a high degree of resistance to dewetting of the terminations during soldering |**Types**<br>~~es~~|**NC 12**<br>**IEC SIZE : 0805**<br>~~es~~<br>~~ee~~|**NC 20**<br>**IEC SIZE : 1206**<br>~~es~~| |---|---|---| |**DIMENSIONS:millimeters (inches)**<br>~~es~~|2 (.079)±0.3 (.012)<br>1.25 (.049)<br>±0.2 (.008)<br>0.5 (.020)<br>... 1.3 (.051)<br>0.2 (.008) min<br>0.2 (.008) min<br>~~es~~<br>~~ee~~|3.2 (.126)±0.4 (.016)<br>0.2 (.008) min<br>0.2 (.008) min<br>1.6 (.063)<br>±0.25 (.010)<br>0.5 (.020)<br>... 1.5 (.059)<br>~~es~~| |Terminations|Silver – palladium – platinum metallization|| |Marking|On packaging only|| |Climatic category<br>~~es~~|40/125/56<br>~~es~~|| |Operating temperature<br>~~es~~|-55°C to +150°C<br>~~es~~|| |Tolerance on Rn (25°C)<br>~~es~~<br>~~a~~|±5%, ±10%, ±20%<br>~~es~~<br>~~a~~|| |Maximum dissipation at 25°C<br>~~a~~|0.12 W<br>~~a~~|0.24 W<br>~~a~~| |Thermal dissipation factor<br>~~a~~<br>~~a~~|2 mW/°C<br>~~a~~<br>~~a~~|4 mW/°C<br>~~a~~<br>~~a~~| |Thermal time constant<br>~~e~~|5 s<br>~~es~~|7 s<br>~~s~~| ##
