TDK SD & SDC Electromagnetic Buzzers

TDK SD and SDC Electromagnetic Buzzers deliver high reliability and are available with or without an oscillator circuit. The SD series features compact, pin-terminal type electromagnetic buzzers with 2048Hz output ideal for automobile equipment. The pin-type terminal construction enables direct mounting onto printed circuit boards. TDK SDC Electromagnetic Buzzers feature a built-in oscillator circuit so output can be produced by merely connecting to a DC power supply. This circuitry utilizes chip-type components for a significantly reduced size and high reliability.
