Sp\u00e9cifications techniques<\/h2>\n

Notre noyau de microphone \u00e9lectret unidirectionnel 9745 est dot\u00e9 de condensateurs doubles externes et de billes anti-interf\u00e9rences pour une protection efficace contre les interf\u00e9rences RF et haute fr\u00e9quence. La t\u00eate de microphone enti\u00e8rement blind\u00e9e de 9 mm utilise un JFET Panasonic de haute qualit\u00e9, garantissant des performances stables et fiables.<\/p>\n

Circuit d'essai standard<\/h3>\n

\"Circuit<\/p>\n

\nConditions d'essai : RL = 680\u03a9, Vs = 1,5V, C = 1\u03bcF.\n<\/p>\n

R\u00e9ponse en fr\u00e9quence typique<\/h3>\n

\"R\u00e9ponse<\/p>\n

\nCouvre une gamme de fr\u00e9quences de 100Hz \u00e0 12kHz. La courbe pr\u00e9sente une augmentation progressive de 100 Hz \u00e0 1 kHz, reste relativement plate entre 1 kHz et 5 kHz, puis commence \u00e0 d\u00e9cliner au-del\u00e0 de 5 kHz.
