The MLT-4020H from MEIDI is a 12Ω 3V 4*4*2mm SMD Magnetic Passive Buzzer, delivering ≥65 dB at 4 kHz. Ideal for IoT, wearables, and portable medical devices. Request a quote or order samples today for your next design. OEM customization available for bulk orders.

MEIDI MLT-9650Y-5V is a 5V 9.6*9.6*5mm SMD Magnetic Active Buzzer. Built with an integrated oscillator, it produces ≥85 dB at 3 kHz without needing external PWM circuitry. Simply apply DC voltage and the unit generates sound immediately. Its 4–7 V operating range works with both 5V logic rails and industrial bus systems. The extended -30 °C to +70 °C temperature rating makes it suitable for outdoor installations and cold-chain environments. Request a quotation or order free evaluation samples today. OEM customization and volume pricing are both available.

MEIDI HNR-1407PA75 — a 1407 Piezoelectric Passive Buzzer with Pogo Pin delivering measured 89–94 dB at 4000 Hz. The 14 mm diameter hits a sweet spot between 12.5 mm compact and 22 mm large formats, offering 25% more diaphragm area than 12 mm alternatives without the footprint penalty of 22 mm devices. Operates 1–30 V with 0.63–0.78 mA draw. The 6.7 mm slim profile and 0.85 g mass suit mid-size portable and IoT applications. Black PBT housing rated for 260 °C wave soldering. Request samples or submit RFQ for volume pricing.

MEIDI HNR-1255 PA5.0 is a spring-loaded piezoelectric passive buzzer with pogo pins, measuring 12.5 × 5.5 mm. It operates across 1–30 V and draws only 0.63–0.78 mA. Standing 5.5 mm tall, it cuts 21% off the height of typical 7.0 mm alternatives yet still delivers the same ≥80 dB output at 4000 Hz. Its 12 nF capacitive load pairs well with low-voltage MCU PWM drives. At just 0.60 g, this buzzer targets wearables and space-critical IoT designs. The black PBT housing handles 260 °C wave soldering. Request samples or send an RFQ for volume procurement.

MEIDI HNR-1207 PA6.5 — a 12.5×7.0 mm Piezoelectric Passive Buzzer with Spring-Loaded Pogo Pins with an exceptionally wide 1–30 V operating range and sub-milliampere current draw. Delivers ≥80 dB at 4000 Hz with only 0.45–0.54 mA consumption under 5 Vp-p square wave drive. The 10 nF capacitive load enables direct MCU GPIO drive without external transistors in most 3.3 V and 5 V designs. Weighing 0.66 g, it suits wearable, portable, and battery-critical applications where every milliamp counts. Black PBT housing rated for 260 °C wave soldering. Request samples or submit RFQ for volume pricing.

MEIDI 12*5.5mm Piezoelectric Passive Buzzer — 12.5×5.5 mm through-hole piezoelectric passive buzzers with 1–30V ultra-wide drive range and 4000 Hz resonance. PA5.0 and PA6.5 variants share one electrical platform, offering selectable lead lengths for flush or elevated mounting without BOM redesign. ≤10 mA consumption and ≥80 dB output suit battery meters, medical handhelds, and 12V/24V industrial nodes.
