The MEIDI HNR-1404 PA7.5 1404 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. It runs on an external AC signal, usually a square wave or PWM near its 4000 Hz resonance, to produce clear audible output. The 1–30 V peak-to-peak drive range works with diverse signal sources, and 5 V serves as the rated test reference. Measuring Φ13.8 × 4.0 mm and weighing 0.67 g, its compact form and black PBT housing support manual soldering for bulk production assembly. Well-suited for procurement across consumer electronics and industrial controls, you can contact MEIDI for technical queries, samples, or volume pricing.

The 1255 Piezoelectric Passive Buzzer with Pogo Pin is a piezoelectric passive buzzer in a through-hole mounting configuration. As a passive device, it requires an external AC drive signal — typically a square wave or PWM at or near the resonant frequency of 4000 ± 500 Hz — to generate audible output.
The 1–30 V operating voltage range is specified for the drive signal peak-to-peak amplitude. The rated voltage is 5 V for test condition reference.
The 12.5 ± 0.3 mm diameter and 5.5 ± 0.5 mm height define the through-hole mechanical envelope. The body mass is 0.60 ± 0.2 g. The black PBT housing material is specified for compatibility with the wave soldering and manual soldering temperature profiles listed in the product specification.

The MEIDI HNR-1707 PA10 1707 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. It runs on an external AC signal, typically a square wave or PWM around its 4000 Hz resonance, to generate audible output. With a 1–30 V peak-to-peak drive range and 5 V rated test voltage, this buzzer measures Φ17.0 × 7.5 mm and weighs 1.35 g. Its black PBT housing supports both wave and manual soldering for smooth integration into **supplier** production lines. Suitable for **batch orders** across audio alert and industrial systems, contact MEIDI for technical questions, sample evaluation, or volume pricing.

The MLT-9018 is a 5V 4000Hz SMD piezoelectric passive buzzer with a 9.0 × 9.0 × 1.8 mm footprint. A passive device, it needs an external AC drive, commonly a square wave or PWM near resonance, to produce sound. Built on ceramic piezoelectric technology rather than electromagnetic coils, 9×9×1.8mm SMD Piezoelectric Passive Buzzer draws ≤5 mA and produces no inductive kickback. The 1–25V operating range yields ≥70 dB at the 5V rating, with 12000 ± 30% pF capacitance. At 0.4 g in a black LCP housing, it withstands 255 °C reflow up to three passes, fitting standard supplier assembly lines. For bulk purchases in space-constrained designs, MEIDI's Applications Engineering department offers tailored driver circuit recommendations, making it an ideal choice.

MEIDI's 5V 2700Hz SMD Magnetic Active Buzzer is a 5V 2700Hz SMD electromagnetic active buzzer packing an onboard drive circuit. At 12.8 × 12.8 × 6.5 mm, it emits a steady tone once 4–7V DC is applied, requiring no external waveform or driver — just a GPIO output or basic DC line. Delivering ≥85 dB at 10 cm with its 5V rating, this unit features a deeper 2700 Hz resonance than common 4 kHz models. It operates reliably from -40 °C to +105 °C, and its LCP housing withstands up to three reflow cycles for efficient production scaling. Well-suited for bulk procurement across industrial and consumer electronics, reach out to MEIDI applications engineering for integration advice or pricing.

The MEIDI MLT-8530H Series includes two electromagnetic passive buzzers built on the same 8.5 × 8.5 × 3.0 mm platform. The 16R variant runs at 16 Ω / 3.6V rated, and the 32R at 32 Ω / 5V rated — only coil impedance and voltage differ, so teams can test drive schemes without reworking the PCB. Both need an external AC drive near 2700 Hz to sound, giving firmware control over tone and patterns. Each 8.5*8.5*3mm SMD Magnetic Passive Buzzer delivers ≥85 dB at its rated voltage. At 0.5 g with an LCP housing, they support up to three reflow passes for smooth assembly workflows.
