MLT-8530
Category
The MLT-8530 is a cost-effective 80dB electromagnetic buzzer with 2.7kHz frequency in an 8.5x8.5mm SMD package, suitable for industrial alarms and automotive alerts. It operates at 2.5-4.5V with 15mA current limit, requires careful SMD soldering and thermal management, and is RoHS compliant. Designers should ensure proper layout clearance, use 3.3-5V drivers, and validate cycle reliability. Market strengths include competitive pricing and high SPL, while limitations are fixed frequency and lack of integrated driver.
