ACMQ9767BT-46

RYD ACMQ9767BT-46 is a Φ9.7×6.7mm omnidirectional electret condenser microphone with ultra-low ≤0.4mA (<400μA) current consumption specifically designed for battery-powered smart video doorbells. -46±3dB sensitivity, 60dB SNR, 50Hz–16kHz response, 4.5V operation. Minimizes standby drain to extend battery service intervals from months to years in always-listening doorbell designs. Largest diaphragm compensates for lower sensitivity with superior acoustic stability. Solder terminal for compact doorbell PCB. Manufactured under RYD ISO9001 with RoHS compliant materials. Customization available: sleep-mode current validation, custom low-leakage FET screening, battery voltage brownout compatibility, UV-resistant housing, and IP54 weather protection. Directly addresses the #1 battery doorbell design challenge: balancing voice performance with multi-year battery life.
