The 9.2 x 2.7mm 3V 16ohm 85dB SMT magnetic transducer buzzer is designed for compact electronic products that require practical audible output in a surface-mount format. The product page describes it as a super loud SMD buzzer and identifies household buzzer as a key application direction. This makes it suitable for compact home electronics, prompt devices, and low-cost electronic products that need clear sound feedback in a limited space.
Compared with very small low-SPL models, this buzzer offers a practical 85dB minimum sound output at 10cm while keeping a compact footprint. For many household products and small electronic modules, that balance of sound level, size, and cost is especially useful.
The buzzer also uses PPS housing material, which may be relevant for product designers considering mechanical characteristics, heat resistance, or manufacturing stability in SMT assembly processes.
The 9.2 x 2.7mm compact SMT structure makes this buzzer suitable for modern household electronics, compact appliance modules, and small electronic assemblies. It fits into limited PCB layouts while still offering useful prompt sound output.
With a minimum sound output of 85dB at 10cm, this buzzer provides practical audible feedback for household devices and compact products. It is strong enough for prompt or reminder functions without requiring the size of a larger warning buzzer.
The rated voltage is 3V, and the operating range is 2V to 5V. This allows the component to fit a wide variety of low-voltage electronics and compact control modules.
The 16 ohm coil resistance and current consumption of 80mA maximum make the buzzer practical for applications where circuit matching and electrical efficiency are both important.
The product uses PPS housing material, which supports practical use in SMT manufacturing environments and can be an important consideration for product designers evaluating component durability and processing compatibility.
The description highlights low-cost SMT electromagnetic transducer buzzer positioning, which makes this model attractive for electronics projects where sound function, compact size, and budget all need to be balanced.
Household and small consumer electronic products often need reliable prompt sounds but do not necessarily require very large alarm buzzers. An SMT magnetic transducer buzzer like this one offers a practical solution because it combines compact size, usable sound output, and compatibility with automated PCB assembly.
For low-cost product lines, the right buzzer should also be easy to source, easy to integrate, and stable enough for repeat production. This model is positioned well for those needs.
This 9.2 x 2.7mm 3V 16ohm 85dB SMT magnetic transducer buzzer can be used in:
· Household electronic products
· Small appliance modules
· Prompt and reminder devices
· Compact control units
· Low-cost electronic products
· Surface-mount PCB modules
· Portable consumer electronics
· Compact notification units
Its application profile is especially suitable for products that need clear prompt sound in a compact and cost-effective SMT package.
OEM buyers usually want a buzzer that is compact, practical, easy to assemble, and cost-effective. This model fits those requirements by combining a manageable size, 85dB sound output, and SMT compatibility. It is suitable for both product development evaluation and ongoing production supply.
