Introducing DB Unlimited’s TE054003-1

As a result of DB Unlimited’s dedication to technology and innovation, we have come up with a way to get 78 dBA out of a 5x5x2mm package. The TE054003-1 is one of the smallest surface mount audio transducers on the market today. It offers all of the versatility and performance customers have come to appreciate from an electrical mechanical transducer, while taking up the least amount of space on the PCB.

With a wide range of acceptable frequencies, the customer can choose between everything from a “click” to a wide range of “beeps” and “tones”. This product is perfect for any small handheld device or any device design where space is a premium.
