These 27mm discs feature a feedback electrode and 3.93" (100mm) leads. Feedback Electrodes are used to construct buzzers, but do not have to be used. To use these in the more conventional sense (pickups, mics, etc..), simply leave the blue lead disconnected.
Resonant Frequency 4.6KHz. Resonant Resistance 300 ohm max. Capacitance 16,000pF +/- 30%.
