Elecret Condenser Mic Model. Voltage Controlled Current Source represents JFET within electret mic body.


3-wire configuration shown.

Default Mic Specs: Sensitivity: -42 dB at 1 kHz (0dB = 1 V/Pa, Vcc = 5 V, Rs = 5.6 kohm) Current Consumption: 600 uA Max SPL = 136 dB SPL (126.2 Pa)

For k: 7.9mV/Pa * 1/5.6kohm = 1.417uA/Pa (replace Pa w/ Volts)

For VE: 600uA / 1.417uA/Pa = 423.43V
