CUI Inc.’s Components Group has extended its range of micro-buzzers with three new models housed in compact, surface-mount packages, of which the smallest has a footprint of just 4mm x 4mm.
Offering audio outputs at Sound Pressure Levels (SPL) ranging from 65dB to 80dB at a distance of 10cm, these micro-buzzers are ideal for use in portable equipment.
The CMT-4023S-SMT and CMT- 5023S-SMT are magnetic transducer buzzers with a compact footprint of 4mm x 4mm and 5mm x 5mm respectively. Both buzzers have a low profile of 2mm, a rated voltage of 3V and a frequency of 4kHz.
The CMT-4023S-SMT is among the smallest buzzers in the industry, and offers an SPL of 70dB while operating over a temperature range of -20°C to 70°C.
The CMT-5023S-SMT features an SPL of 80dB with an operating temperature range of -30°C to 70°C.
For applications in which electrical noise needs to be kept to a minimum, the 9mm x 9mm CPT-9019S-SMT features piezoelectric technology. With a profile of 1.9mm, it is one of the lowest-profile piezo buzzers on the market.
The CPT-9019S-SMT features a maximum peak-to-peak voltage of 25V, a frequency of 4kHz and an SPL of 65dB. The operating- temperature range for the CPT-9019S-SMT is -30°C to 70°C.
All three models are externally driven and suitable for use in designs requiring reflow solder assembly for high-volume production.
