CUI’s Components Group recently expanded its micro buzzer product line. Housed in surface-mount packages as small as 4 mm × 4 mm, the three new models—CMT 4023S SMT, CMT 5023S SMT, and CPT 9019S SMT—are well suited for a wide variety of portable electronic systems.
The CMT 4023S SMT and CMT 5023S SMT magnetic transducer buzzers are 4 mm × 4 mm and 5 mm × 5 mm, respectively. They have a rated voltage of 3 V and a rated frequency of 4 kHz.
The 9 mm × 9 mm CPT 9019S SMT features piezoelectric technology and a profile depth of 1.9 mm. The series delivers a maximum peak-to-peak voltage of 25 V, a rated frequency of 4 kHz, and an SPL of 65 dB. Its operating temperature range is –30°C to 70°C.
The CMT 4023S SMT, CMT 5023S SMT, and CPT 9019S SMT are externally driven and suitable for use in designs requiring reflow solder assembly for high-volume production. They are available immediately with prices starting at $1.08 per unit in 1,000-piece quantities.
