Electrical capacitance: Measured at 1 V_pp, 1 kHz, room temperature.

Resonant frequency, unloaded: Measured at 1 V_pp, unclamped. The value is halved for unilateral clamping.

Leakage current: < 1 µA, typically < 100 nA, measured at 100 V, after 5 min, room temperature, 60 % relative humidity.

Resistance: > 10 GΩ, laboratory measurement at room temperature or at an elevated temperature of up to 100 °C.

AC service life: > 6 × 10^8 cycles, measured under 8 MPa preload, 0 to 120 V, 116 Hz sine wave.

DC lifetime (MTTF): > 7 × 10^4 h, extrapolated at 150 V, room temperature.

Custom versions or different specifications on request.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
