Description
£±¡¢Model No
¡¡¡¡¡¡The Model No.of Buzzer Chips is compose of
¡¡¡¡¡¡six parts(see the picture)£©,piezo ceramic element¡£
£²¡¢Illustration
¡¡¡¡¡¡the first part:"FT" indicate Piezoeletric
¡¡¡¡¡¡Ceramic Buzzer Chips,piezo ceramic element
¡¡¡¡¡¡the second part:use the Arab figure to
¡¡¡¡¡¡express plate exotic dismeter(mm)
¡¡¡¡¡¡the third part:use denominator to express
¡¡¡¡¡¡plate material;For example:
¡¡¡¡¡¡T-brass,G-stainless steel,N-iron and nickel
¡¡¡¡¡¡alloy,M-horse mouth iron
¡¡¡¡¡¡the fourth part:use the Arab figure to
¡¡¡¡¡¡express frequency(kHz)
¡¡¡¡¡¡the fifth part:use denominator to express
¡¡¡¡¡¡electrode shape;For example:
¡¡¡¡¡¡A-round,B-partition shape,C-square,D-
¡¡¡¡¡¡unnormal shape
¡¡¡¡¡¡the sixth part:use the Arab figure to
¡¡¡¡¡¡express structure;For example:
¡¡¡¡¡¡1-single side,2-double sides
¡¡3.Paradigm
¡¡¡¡¡¡For example:piezoeletric ceramic buzzer
¡¡¡¡¡¡chips FT-27T-4.1A1 Q/WZOX 1-2002.piezo ceramic element.
¡¡¡¡¡¡The example indicate:the piezoeletric
¡¡¡¡¡¡ceramic buzzer chips'plate exotic dismeter
¡¡¡¡¡¡is 27mm and brass,resonant frequency is
¡¡¡¡¡¡4.1kHz,round electrode and single side.And
¡¡¡¡¡¡the product's normal code is Q/WZOX 1-2002.Model NOResonant
