Notes:
We describe the fabrication of chip-type PTC elements (BaTiO3-based) by roll-formingprocess. Crack-free green tapes with good malleability are successfully obtained with the thicknesstypically in the range of 0.20~1.0mm. We also focus on reducing the room-temperature resistance of thechip-type PTC element without deteriorating its PTC effect, both by controlling the firing schedule and byintroducing multilayer structure with electrode-bonding method. The typical size of the 5-layeredchip-type PTC sample obtained is 8.0mm×5.0mm×1.95mm with R25=1.97- and Rmax/Rmin=4.8×105
