Surface-mountable negative-characteristic ceramic thermistor based on Mn, Co, Ni and Ti compounds

摘要

A surface-mountable negative-characteristic ceramic thermistor (1) based on a ceramic compound composed of a semiconductor ceramic material containing Mn, Ni, Co, and Ti. External electrodes are disposed on surfaces of the ceramic body and plating films are disposed on the external electrodes.;The semiconductor ceramic material is composed of Mangan (Mn), nickel (Ni), Cobalt (Co), and Titan (Ti),;- the content of (Mn) is in the range of 0.1 mol% to 90 mol%,;- the content of (Ni) is in the range of 0.1 mol% to 45 mol%, and;- the content of Cobalt (Co) is in the range of 0.1 mol% to 90 mol%, provided that the sum of Mn, Ni, and Co is 100 mol%.;When the total molar quantity of Mn, Ni and Co in the semiconductor ceramic material is defined as being 100 parts by mole,;-the added content of Ti is in the range of 0.5 parts by mole to 30 parts by mole.
