I've managed to find these specifications from the Maplin website which are
the same capsules I have.
Type EM-60B is a sub-miniature omni-directional electret condenser
microphone only 9· 8mm diameter and 7mm thick.
Specifications:
Response: Omni-directional
Frequency response: 50Hz to 13kHz
Sensitivity: -60dB ±3dB
(0dB = 1V/µbar at 1kHz, Vcc = 4· 5V, Rl = 1k)
Impedance: 1k maximum
S/N ratio: >40dB
Sound pressure level: 120dB maximum
Power supply: 1· 5V to 10V DC
Recommended voltage: 4· 5V (optimum performance)
Current drain: <0· 4mA
