Type: Piezo Ceramic Element
Product Name: piezo ceramic element,Internal Type,External Type
Description:
　

１、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.
