A Nice Unit, But Watch Polarity
Characterized 320 of these units. Manufacturing tolerances are pretty tight overall. Average values for 320 units:
Clamping (DC) Capacitance (C0): 2.81 nF
Fctr: 24.495 kHz
BW (3dB): 906 Hz

Watch polarity, however. Some of these units are connected 'backward' internally. Two otherwise identical units will, for example, under identical circumstances produce (as receivers) electrical outputs that are 180 degrees out-of-phase. In some applications correct phasing is important, so beware.

All 320 units functioned satisfactorily at 21 Vp-p (sine) drive levels. 21 Vp-p seems to be the max drive level for this style of PZT, but there isn't much literature available Out There for these 24 kHz units (most extant literature - such as it is - centers on the more commonly available 40 kHz units).

Btw: I selected a handful of units for destructive testing and found that several units survived up to 122 Vp-p drive levels at resonance for the two-hour duration of this part of my tests. Several units 'bought the farm' at less than 35Vp-p drive levels, so I would assume the max drive levels for rest of the lot are probably 'all over the map' as well.

Hope this info was helpful.

3 lobe cardioid
24.50khz +/- 0.25khz is the range, beyond which it's dead. Has a 3 lobe cardioid pattern. Sharp cutoff near 30 deg off center, then it picks up again. Ran it up to 20V p-p without issue. Leads fit standard proto boards without any force. Shroud easily comes off by destroying the metal nubs, giving you a look inside. No plastic in this part, so the leads don't slide up & down when you solder them.

Is a datasheet out there?
I'd like to design this part in and having a datasheet on hand would be helpful. Is there one out there anywhere?
