Electret Condenser Microphones characterizes small size, wide sensitivity range and frequency response, high SNR, low THD, fine sound quality, low cost.

With these qualities, ECM is the most common and popular component used in wire/wireless communication devices, digital camera, camcorder, notebook PCs, multimedia products …

If traditional ECM can only be soldered manually, SMD ECM are now available which are compatible with SMT process and reflow temperature.

Thanks to a large selection of ECMs from 10mm diameter to less than 4mm and various connection system (Solder pad, Pin, SMD, cable…), Seltech provide all the flexibility to match to most of the applications.
