Micro Buzzer Line Includes 4 x 4 mm Packages

CUI’s Components Group is adding the CMT-4023S-SMT, CMT-5023S-SMT and CPT-9019S-SMT to their line of micro buzzers. Housed in compact, SMT packages as small as 4 x 4 mm, the devices feature profile depths as low as 1.9 mm and SPL ranging from 65 up to 80 dB at 10 cm.

The CMT-4023S-SMT and CMT-5023S-SMT are magnetic transducer buzzers with a profile of 2 mm, a rated voltage of 3 V and a rated frequency of 4 kHz. The 4 x 4 mm CMT-4023S-SMT carries an SPL of 70 dB and an operating temperature range of -20°C to 70°C. The 5 x 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 x 9 mm CPT-9019S-SMT features piezoelectric technology, a 1.9 mm profile depth, 25 V maximum peak-to-peak voltage and a -30°C to 70°C operating temperature range.

All three models are externally driven, have a 4 kHz rated frequency and are suited for designs requiring reflow solder assembly for high-volume production. The new micro buzzers are available immediately, stock to 8 weeks, with prices starting at $1.08 each/1,000.
