SWT Best‑Selling Piezoelectric Buzzer｜PED30160B32090PAAA

Industry Background: Market Demand for High‑Performance Piezoelectric Buzzers

In the global electro‑acoustic component industry, piezoelectric buzzers play an irreplaceable role in equipment prompt notification and fault alarm. As home appliances, industrial control units, security alarm systems and medical electronic products keep iterating, OEM manufacturers are raising stricter standards for buzzer performance. Many low‑cost alternatives on the market have obvious drawbacks such as fluctuating sound output, limited voltage compatibility and weak temperature resistance. These defects may trigger abnormal alarm signals and even whole‑machine malfunction in end‑products. For overseas purchasers, selecting proven hot‑selling buzzer models with stable batch quality is the key to reducing project risks. As one of SWT’s flagship hot‑sale items, the PED30160B32090PAAA through‑hole piezoelectric buzzer gains massive orders from South Asia, Southeast Asia and other overseas regions due to balanced performance and competitive factory pricing.

Core Electrical & Acoustic Performance of PED30160B32090PAAA

This popular pin‑type piezoelectric buzzer features a resonant frequency of 3.25±0.4 kHz, which perfectly fits common alarm and reminder frequency requirements for consumer and industrial electronics. Its rated peak‑to‑peak voltage is 9 V, while the wide operating voltage range reaches 1‑40 V (Vo‑p), bringing great flexibility for circuit design. Tested by CRY 6125 electro‑acoustic tester at 300 cm distance, its minimum sound output reaches ≥90 dB to deliver loud and clear alert tones. The maximum current consumption is controlled within 15 mA, helping customers cut total power consumption of finished devices. The main‑electrode capacitance measured at 120 Hz is 28 nF with ±30% tolerance. All parameters are validated by high‑precision test instruments including TH2816B LCR meter and Agilent 34401A multimeter.

Structural Features & Environmental Adaptability

The outer diameter of this buzzer is φ30.5±0.5 mm. It adopts an integrated sturdy plastic housing with through‑hole pin terminals for convenient PCB soldering assembly. The optimized housing structure delivers good shock‑resistance performance, adapting to equipment scenarios with mechanical vibration. For temperature resistance, both operating temperature and storage temperature range from ‑40 ℃ to +85 ℃. It can maintain stable sound output under extreme cold or high‑temperature working conditions, preventing sound drop‑off and functional failure caused by harsh ambient conditions.

Wide Application & Procurement Support

As SWT’s well‑recognized hot‑selling piezoelectric buzzer, this model is widely applied in household appliance prompt modules, industrial control panel alarms, anti‑theft security systems, fire warning equipment and portable medical instruments. It supports small‑batch sample testing as well as large‑scale bulk orders. With stable production capacity, strict quality inspection, direct factory price and reliable delivery schedule, it becomes a preferred choice for international importers and electronic assembly factories.
