摘要：
Ink jet printheads and printhead components having a body that include a flow path, a piezoelectric actuator having a piezoelectric layer fixed to the body and an impedance feature in the flow path are described. The impedance feature includes a plurality of posts arranged in a first row, at least one post in the first row of posts having a downstream surface that is concave.
