CUI’s Components Group has several new additions to its range of micro buzzers. The three newer models are housed in compact, surface mount packages as small as 4 x 4mm. Featuring profile depths as low as 1.9mm and sound pressure levels (SPL) ranging from 65dB up to 80dB at 10cm, these micro buzzers are ideal for a range of portable equipment applications.
The CMT-4023S-SMT and CMT-5023S-SMT are magnetic transducer buzzers housed in compact footprints of 4 x 4mm and 5 x 5mm, respectively. Both buzzers feature a low profile of 2mm, a rated voltage of 3V and a rated frequency of 4kHz.
The CMT-4023S-SMT with its 4 x 4mm package is among the smallest in the industry while carrying an SPL of 70dB and an operating temperature range of -20°C to +70°C.
The 5mm CMT-5023S-SMT features an SPL of 80dB with an operating temperature range of -30°C to +70°C.
For applications where electrical noise is more of a concern, the 9 x 9mm CPT-9019S-SMT features piezoelectric technology and a profile depth of 1.9mm – making it one of the lowest profile piezo buzzers on the market.
The operating temperature range for the CPT-9019S-SMT is -30°C to +70°C. The series delivers a maximum peak-to-peak voltage of 25V, a rated frequency of 4kHz and an SPL of 65dB.
All three models are externally driven and suitable for use in designs requiring reflow solder assembly for high-volume production.
