The MSR205NSR is a PCB-mount audible sounder designed to produce a continuous tone. It operates on a voltage range of 2 to 5 VDC with a maximum current draw of 10mA. This device generates a typical sound level of 85 dB(A) at 1 foot with a frequency of 3900 ± 500 Hz. Built to withstand a wide temperature range from -40°C to +85°C, it is housed in a blue VALOX (UL94V-0) material. Its design is suitable for wave soldering, making it ideal for various electronic assemblies requiring a reliable audible indicator.
