Featuring two acoustic output tiers in one shared form factor, the MEIDI 14*4mm Piezoelectric Passive Buzzer series streamlines procurement for design teams. Both variants measure Φ13.8 × 4.0 mm and resonate at 4000 Hz, so engineers can swap sound pressure levels without reworking PCB layouts or drive circuitry. The standard HNR-1404 produces ≥70 dB while drawing ≤5 mA; the high-output HNR-1404 PA7.5 reaches ≥80 dB at ≤10 mA. Each runs on external square-wave or PWM signals spanning 1 V to 30 V, supporting adjustable tones through drive parameter changes. Supplied with a coil-free piezoelectric build — well-suited for magnetically sensitive environments — these buzzers come in black PBT housings with through-hole pins and are compatible with manual soldering.

The 1207 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. As a passive unit, it relies on an external AC drive — typically a square wave or PWM around its 4000 ± 500 Hz resonance — to produce audible output. Its drive signal spans 1–30 V peak-to-peak, giving circuit designers wide voltage flexibility without tight regulation. The 5 V rated voltage serves as the test reference. Measuring Φ12.5 × 7.0 mm and weighing 0.66 g, the black PBT housing suits both wave and manual soldering profiles. Its coil-free piezoelectric architecture sets it apart from electromagnetic buzzers, with no magnetic coil or moving armature inside — well-suited for sourcing into magnetically sensitive assemblies. Contact MEIDI for technical support, sample evaluation, or volume pricing.

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.
