| Dimensions(mm) | Capacity C(pF) | Weak field dissipation Tgδ (12v) | Strong field dissipation Tgδ (400v) | Radial frequency Fr(KHz) | Resonance impedance Zm() | Thick frequency Ft(KHz) | Coupling modulus Kr(%) | Quality factor Qm |
| Φ 10/Φ 5*2 | 240± 10% | ≤ 0.5% | ≤ 1.0% | 153± 5% | ≤ 15 | 1020 | ≥ 45 | ≥ 800 |
Piezoceramic components, such as plates, disks or rings, convert mechanical signals, such as force, pressure, strain or acceleration, into electrical voltage, or, vice versa, an electrical voltage into mechanical motion or oscillations. The typical resonant frequencies are between 200 kHz and 10 MHz. The piezo elements are frequently used for generating ultrasonic oscillations, for example, in sensors or for high-power ultrasonic applications.
