SDRP27P8-50P100

RYD SDRP27P8-50P100 Φ27mm High-Impedance Audio Driver for Medical Devices and Telecommunications. Engineered with 100±15%Ω impedance for compatibility with legacy telecom circuits and high-impedance audio lines, this Φ27×7.5mm receiver delivers 115±3dB SPL (IEC318 coupler, 178mV) across 100Hz–4kHz. Rated power is 50mW with THD 5% max at 1kHz/0.1V. Operating temperature range is -20℃ to +55℃. The high-impedance design minimizes current draw, which is advantageous for battery-powered medical monitoring instruments, bedside communication devices, and legacy telephone equipment requiring stable voice output without additional amplification stages.
