61 nb12, surface mount 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 achieve temperature control of printed circuits. its silver - palladium - platinum metallization provides a high degree of resistance to dewetting of the terminations during soldering (typically 260? / 30 s). how to order nc 20 type k 0 material code k 0103 resistance 10,000 ? m tolerance m (?0%) j (?%) k (?0%) ba suffix: packaging ?? bulk ba: plastic tape (180mm diam. reel) be: plastic tape (1/2 reel) bc: plastic tape (330mm diam. reel) bb: cardboard tape (180mm diam. reel) bf: cardboard tape (1/2 reel) bd: cardboard tape (330mm diam. reel) nc 12 iec size : 0805 types rn at 25? material b (k) at 25?
