| titleOfInvention | Compositions for thick film resistors, pastes for thick film resistors, and thick film resistors |
| abstract | PROBLEM TO BE SOLVED: To provide a composition for a thick film resistor which does not contain a lead component having excellent resistance temperature coefficient and noise characteristics. SOLUTION: It does not contain a lead component and contains ruthenium oxide powder, glass powder, and mixed oxide powder of alumina and silica. The glass powder contains SiO 2 and B 2 O 3 and RO (R represents one or more alkaline earth elements selected from Ca, Sr and Ba), and the SiO 2 and B 2 O 3 and RO. When the total content is 100 parts by mass, SiO 2 is 10 parts by mass or more and 50 parts by mass or less, B 2 O 3 is 8 parts by mass or more and 30 parts by mass or less, and RO is 40 parts by mass or more and 65 parts by mass or less. Content in proportion, The mixed oxide powder of alumina and silica has a specific surface area of 60 m 2 / g or more and 300 m 2 / g or less. A composition for a thick film resistor containing 1 part by mass or more and 12 parts by mass or less of a mixed oxide powder of alumina and silica when the total content of ruthenium oxide powder and glass powder is 100 parts by mass. provide. [Selection diagram] None |
