EPCOS / TDK B58004 Passivated HAS Multilayer Piezo Actuators
TDK B58004 Passivated High Active Stack (HAS) Multilayer Piezo Actuators offer a highly efficient, robust design that avoids polarization cracks with the help of small insulation zones. The B58004 are made off RoHS-compatible lead zirconate titanate (PZT) with an internal copper electrode. The actuators provide high cycle stability at high temperatures, a high melting metal bond, and resistance against humidity. Other features include copper inner electrodes, 160V polarization, and a capacitance of 3.0µF (typical) in a ceramic body measuring 5.2mm x 5.2mm x 30mm.
