CUI’s Components Group today announced several new additions to its range of micro buzzers. The three new models are housed in compact, surface mount packages as small as 4 mm x 4 mm. Featuring profile depths as low as 1.9 mm and sound pressure levels (SPL) ranging from 65 dB up to 80 dB at 10 cm, 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 mm x 4 mm and 5 mm x 5 mm, respectively. Both buzzers feature a low profile of 2 mm, a rated voltage of 3 V and a rated frequency of 4 kHz. The CMT-4023S-SMT with its 4 mm x 4 mm package is among the smallest in the industry while carrying an SPL of 70 dB and an operating temperature range of -20°C to 70°C. The 5 mm CMT-5023S-SMT features an SPL of 80 dB with an operating temperature range of -30°C to 70°C. For applications where electrical noise is more of a concern, the 9 mm x 9 mm CPT-9019S-SMT features piezoelectric technology and a profile depth of 1.9 mm – making it one of the lowest profile piezo buzzers on the market. The series delivers a maximum peak-to-peak voltage of 25 V, a rated frequency of 4 kHz and an SPL of 65 dB. 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.
The CMT-4023S-SMT, CMT-5023S-SMT and CPT-9019S-SMT are available immediately through distribution with prices starting at $1.08 per unit at 1,000 pieces. Please contact CUI for OEM pricing.
