The 10 x 10 x 3.3mm 18 OHM 2830 HZ SMD transducer is a compact passive magnetic sound component developed for modern SMT-based electronics. It is especially suitable for applications where engineers need a small square transducer with strong audible output and reliable mounting compatibility. The product page identifies it as a 10mm passive magnetic buzzer and also highlights its use in magnetic door lock buzzer applications.
This makes the product attractive for projects such as electronic locks, access control terminals, control boards, portable electronics, and compact alarm modules. Its square 10mm body helps PCB layout planning, while the 95dB minimum sound output at 10cm gives it a strong alert capability relative to its size. For buyers looking for a passive buzzer rather than a self-drive buzzer, this model fits the need for externally driven acoustic control.
Because the product is an SMD transducer, it can support automated SMT assembly in modern production environments. This matters for OEM manufacturers who need efficient large-volume production, consistent placement quality, and reliable integration into space-constrained electronic products.
One of the major strengths of this 10 x 10 x 3.3mm SMD transducer is its high sound output of 95dB minimum at 10cm. For many compact electronic products, it is difficult to obtain strong audible performance without increasing the component footprint. This model offers a practical solution for applications that need stronger sound from a relatively small package.
This model is a passive magnetic buzzer, which means it is suitable for designs where the sound is generated through an external drive circuit. For some engineering projects, passive transducers offer greater control over tone generation, signal behavior, and system-level acoustic design compared with self-driven buzzers.
The rated voltage is 3.6V, and the operating range is 2V to 5V. This makes the transducer practical for compact electronic circuits and control modules. The wider working range gives designers flexibility when integrating it into systems with different voltage management strategies.
The 18 ohm coil resistance and 2830Hz resonant frequency are important technical characteristics for engineers matching the transducer to their driver circuits and sound expectations. These values help define the component's electrical and acoustic behavior in real applications.
The SMD design supports surface-mount assembly, which is important for modern automated production lines. SMT compatibility improves efficiency, placement consistency, and scalability for OEM manufacturers.
The product description specifically mentions use as a magnetic door lock buzzer. Door locks, access control terminals, and smart security devices typically require a compact sounder that can provide clear status tones and alerts. This product is well positioned for those use cases because of its strong SPL and compact square body.
In some products, engineers prefer passive magnetic transducers because they provide more flexibility in sound control and circuit design. A passive transducer can be driven according to the product's signal design, allowing customized tone generation and response behavior. This is useful in products where the buzzer sound is part of a broader system interaction strategy.
Compared with larger traditional sound components, a compact SMD transducer is easier to integrate into dense PCB layouts. Compared with weaker small sounders, a 95dB-capable transducer offers more practical sound performance for applications that need clear user feedback.
This 10 x 10 x 3.3mm 18 OHM 2830 HZ SMD transducer can be used in:
· Electronic door lock systems
· Access control devices
· Portable alarm modules
· Security products
· Industrial control boards
· Consumer electronic devices
· Portable terminals
· Compact signal reminder modules
Its combination of small size, high sound output, and passive drive design makes it useful for products where system-level control and compact packaging are both important.
OEM buyers typically look for more than a basic buzzer spec. They need a component that fits PCB layout constraints, works with the intended drive circuit, provides stable sound performance, and can be sourced with sample support and predictable delivery. This product addresses those concerns with a compact SMT design, clear parameter set, and factory support information.
For developers working on electronic lock products, compact alarms, or access control systems, this model offers a useful balance of strong sound output and manageable size. It is also suitable for projects where passive transducer behavior is preferred over built-in oscillation.
HC Electronic states that products can be customized according to customer needs. For buyers developing products with specific signal behavior, packaging, voltage preferences, or acoustic targets, customization support can reduce design compromises and improve end-product fit. This is especially valuable for OEM and ODM projects.
According to the company information on the website, Hongchang Electronic has manufacturing experience since 1997 and employs nearly 200 staff members, including acoustic engineers. The company also indicates a factory building area of more than 10,000 square meters. For buyers assessing long-term sourcing partners, this supports confidence in production experience, engineering capability, and supply continuity.
The product page states that quality is managed through a complete process system and quality inspection system. This matters because acoustic components must remain consistent from sample to production batch. Variations in sound level, electrical characteristics, or structure can affect the performance of end products such as electronic locks and security devices.
According to the product page, the product must not be washed. Recommended storage conditions are temperature from -10C to +40C and humidity from 15% to 85% RH in a stable environment. The shelf life is listed as six months after delivery under sealed and unopened package conditions.
Once the package is opened, it is recommended to use the products as soon as possible in order to help maintain product characteristics.

If you are looking for a 10 x 10 x 3.3mm 18 OHM 2830 HZ SMD transducer for a compact electronic lock, access control unit, or alarm product, this 10mm passive magnetic buzzer is a strong candidate. It combines a compact SMT footprint with a high sound output of at least 95dB at 10cm, making it suitable for projects where audible clarity matters but installation space is limited.
In many security and access products, the buzzer is a critical user interface element. It confirms operations, provides warning tones, and supports device status communication. For these products, a passive magnetic transducer can be a practical choice because it allows external circuit control while still delivering a strong sound response. This is why terms like magnetic door lock buzzer and 10mm passive magnetic buzzer are highly relevant for this model.
The product offers a 3.6V rated voltage, 2V to 5V operating range, 2830Hz resonant frequency, and 18 ohm coil resistance. These parameters make it useful for integration into compact control electronics and signal circuits. The 95dB minimum sound output is especially attractive for devices that need stronger prompt tones than many smaller low-output transducers can provide.
As an SMD magnetic transducer, this model also supports efficient automated assembly. For OEM manufacturers, SMT compatibility is essential because it improves production efficiency, placement consistency, and scalability for mass production. Combined with sample support and customization capability, this makes the product practical not only from an engineering perspective, but also from a sourcing and manufacturing perspective.
For buyers searching for a surface mount magnetic transducer supplier, an 18 ohm SMD buzzer manufacturer, or a compact passive buzzer for door lock applications, this model fits well within those use cases. It offers the size, SPL, and parameter profile needed for compact security and control products while maintaining factory-backed sourcing support.
Whether you are developing a smart lock, access terminal, portable alarm module, or small industrial control board, this 10 x 10 x 3.3mm SMD transducer provides a practical balance of size, sound output, and SMT production compatibility.
