Ceramic piezoelectric transformer has outer electrode contacting the iner electrode layer in the region of a side edge of the body

摘要

The transformer has a piezoelectric, preferably PZT ceramic, body and an inner electrode layer (21,22,31,32). An outer electrode (81, 82, 83, 84) contacts the electrode layer in the region of a side edge (41, 42, 43, 44) of the body. A bridge is formed between the side edge and the electrode layer projecting from the side edge.
