    Piezo Ceramic Element

  • 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.
