MURATA PKMCS1818E20A0-R1 piezoelectric sounder for automotive applications enables reflow mounting as an effective countermeasure against irregular mounting and abnormal sound. Product has a sound pressure level of 100dB at 100mm and measures 18 x 18 x 8mm. Device’s wide operational temperature range means that it can operate in automobile cabin temperatures from -40 to 105 °C. Weighing in at one gram, device uses a simple structure, without a magnet or coil, to reduce the impact of electromagnetic noise on surrounding circuits. http://www.murata.com
