Abstract
A multilayer protective device is made by including a varistor composition (35) between a first plurality of interdigitated electrodes (30, 32) and a capacitor composition (36) between a second plurality of electrodes of the same device. The two compositions are chosen to have optimum sintering temperatures within about 10 percent of each other. Simultaneous sintering solidifies and laminates the two compositions into a single monolithic device.
