Resistor Paste

LEED DZ 430XXXX series Resistor Paste are low value resistive paste designed for heating elements on stainless steel substrate. The first two XX plus 10 is resistivity. The unit is mIC/a . The last two XX plus 100 is TCR (the temperature coefficient of resistance). The unit is ppm/a . It has features of big power intensity, high working temperature and small change of resistance after refiring. The resistivity of DZ430XXXX ranges from 50 ma /a to 500 ma /a while TCR ranges from 300ppm/A C to 3300 ppm/A C. Intermediate resistivity may be obtained by lending the two members of a TCR group. Having good compatibilities with LEED dielectric paste and conductor paste, LEED DZ 430XXXX can directly apply to alumina ceramic substrate for making thick film circuit.
