Title:
RESISTOR COMPOSITION, RESISTOR PASTE CONTAINING SAME, AND THICK-FILM RESISTOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/150890
Kind Code:
A1
Abstract:
The present invention provides: a resistor composition and a resistor paste that contain no lead component and exhibit excellent characteristics of having a near-zero resistance temperature coefficient falling within the range of ±100 ppm/°C; and a thick-film resistor using such a resistor composition or a resistor paste. The resistor composition according to the present invention comprises, as major constituents, lead-free ruthenium-based conductive particles and at least two types of lead-free glass powders, the resistor composition being characterized in that: one of the glass powders is a Si-B-Al-Ba-Zn-O-based glass powder that includes SiO2, B2O3, Al2O3, BaO, and ZnO, and contains 5-12 mass% of B2O3; and another type of the glass powders is a Si-B-Al-Ba-O-based glass powder that includes SiO2, B2O3, Al2O3, and BaO, and contains 14-25 mass% of B2O3.
