Industry Background: Market Needs for Compact Lead‑type Piezo Buzzer
Miniaturization has become a clear trend for modern consumer electronics and small‑size control devices. Designers are looking for compact piezoelectric buzzers that can deliver reliable audible alerts within limited internal space. Many compact buzzers available on the market suffer from low sound output, unstable parameters or poor consistency across batches. Choosing a mature compact buzzer model helps manufacturers cut product‑debugging risks and improve end‑product reliability. This 16.4 mm lead‑wire piezoelectric buzzer is a compact standard product developed by Guangdong SWT. Thanks to its small footprint, wire‑lead connection and stable acoustic performance, this buzzer fits well into space‑constrained electronic equipment projects.

Core Electrical and Acoustic Specifications
This compact 16.4 mm lead‑wire piezoelectric buzzer comes with a resonant frequency of 2.5±0.3 KHz, rated peak‑to‑peak voltage of 6Vp‑p, and a wide operating voltage range of 1‑30 V (Vp‑p). Its maximum current consumption is controlled at 10 mA. The minimum sound output reaches 80 dB when measured at 10 cm distance, providing clear audible warning signals for small‑size devices. Insulation resistance is ≥1 MΩ. Capacitance measured at 1000Hz is 18±30% nF. All parameters are measured under standardized test conditions to guarantee repeatable performance for mass‑production applications.
Structural Features & Environmental Performance
The buzzer adopts lightweight ABS plastic housing with outer dimension φ16.4±0.5 mm and total weight of only 1.2 g. It is fitted with two black lead wires for convenient wiring connection, and one mounting lug for screw fixing during product assembly. For environmental adaptability, the operating temperature ranges from ‑20℃ to +70℃, while storage temperature is from ‑30℃ to +75℃. The datasheet also provides complete lead‑free soldering specifications for reflow soldering and wave soldering, guiding customers for proper assembly operations. Its slim and tiny structure makes it ideal for products with tight internal installation space.
Wide Application & Procurement Support
This 16.4 mm lead‑wire piezoelectric buzzer is widely suitable for small household appliances, handheld portable devices, miniature alarm modules, smart sensor equipment and various compact electronic products.
