SUPPLIER INTRODUCTION


Sanico Banner

Founded in 1978 and headquartered in South Korea, Sanico Electronics is a leading manufacturer of high-quality microphones specifically developed for mobile systems, such as phones, cameras, headsets and many more. The company's MEMS and electronic condensor microphones (ECM) are popular among customers in Korea as well as abroad.





Featured Product
MEMS microphone
The AOS3729A-T42 is a front-type MEMS microphone with analog signal output featuring low impedance, thus very high immunity to RF noise.

Excellent thermal characteristics are realized using a MEMS transducer in conjunction with a tailor-made ASIC allowing for fully automized assembly. Thanks to its small footprint (3.76 x 2.95 x 1.1mm), this microphone is ideally suited for portable devices which require audio input, such as

  • Smartphones, cellular phones
  • Tablets, notebook PCs
  • Ear microphone, (Bluetooth®) headsets
  • Digital still and video cameras
  • Car navigation, black boxes
  • Game devices and more.
