MIL-T-27/74B
Primary impedance: 100 kilohms with approximately 5 V, 400 Hz applied to (1-2) and 50 kilohms across (3-5). Frequency response:
ZS = 100 kilohms (1-2) ZL = 50 kilohms (3-5) ES = 5 V
Reference frequency = 1 kHz.
Frequency range is 100 to 10,000 Hz ±2 dB.
Insertion loss: 1 dB with 10 mW, 400 Hz across (1-2) maximum.. Resonance: Second resonant frequency - 20 kHz minimum. Electrostatic shielding: Voltage ratio, 5:1 minimum at 20 kHz. Polarity: Additive, with terminals 2 and 3 connected.
