I have a self-driven magnetic buzzer that i'm using in a
non-intended fashion. Instead of having the buzzer fully on, I
pulse it at approximately 60Hz, using a PIC, of course (This had
to be done as the buzzer draws just a little more current than the
capacitor-powered supply can provide). Does anyone know the
long-term affects of this on the buzzer life?

        The mfg. rep told me that it would be ok to do so.
However, the buzzer had a lead-time of 12 weeks, so the
board house substituted a "direct replacement" buzzer with
(nearly) the same characteristics. Now, i'm starting to see
more failures than make me comfortable.

        Alternately, does anyone know of a 5Vdc buzzer that
draws under 10mA? Either self-driven (10mA) or one that needs
to be driven (which could draw more instantaneous current, but
the average still needs to be 10mA or less).

Thanks for any help.
