The innovative microphone is Omni-directional having a response frequency of 100 to 20,000 Hz at 60dBA low signal to noise response. It shows an output impedance of 2.2 KÙ at 2.0VDC operating voltage at 0.5mA, in a temperature range of -20°C to +70°C. The device is aluminum shielded and is consistent with RoHS.

Apart from the Electret Microphone, the company’s wide range of ceramic elements, piezo buzzers, receivers, microphones, speakers, ultrasonic sensors, and emitters find wide applications in medical, telecommunications, and product industries across North America. Most of the company’s products are ISO-9002, ISO-9001 and/or QS-9000 authorized, and are produced in China, Taiwan and Korea.
