HITPOINT PB-0925ME-05Q SMD Magnetic Buzzer: A 0.6 g Design for Audible Feedback on High-Density PCBs
Audible notification devices must fit into increasingly compact equipment while meeting sound-output, drive-circuit, and assembly requirements. For development teams, selecting a buzzer means considering its electrical specifications, mechanical placement, and intended operating environment together.
The HITPOINT PB-0925ME-05Q is an SMD magnetic buzzer with a lightweight 0.6 g construction and LCP housing. It provides a minimum sound pressure level of 85 dB at 10 cm with a 5 Vp-p, 2500 Hz drive, making it an option for high-density PCBs, industrial equipment, and audible notification circuits.

Defined Sound-Pressure Performance for Notification Design
The PB-0925ME-05Q provides at least 85 dB SPL at a distance of 10 cm when driven at 5 Vp-p and 2500 Hz. This operating point gives engineers a reference for evaluating audible feedback against the product's listening distance and intended environment.
Sound-pressure performance should be evaluated together with drive voltage, frequency, and measurement distance. A useful development sequence is to characterize the component first, then verify the result in the final enclosure. This keeps electrical design and acoustic requirements aligned.
Lightweight SMD Construction for Compact Equipment
With a weight of 0.6 g, SMD terminals, and an LCP housing, the PB-0925ME-05Q supports integration into densely populated control boards without adding significant component weight.
Engineers can plan buzzer placement and the sound outlet alongside the controller, connectors, and other board functions. Addressing acoustics early in the mechanical design helps avoid relocating components or revising the enclosure late in development.
External Drive Supports Application-Controlled Notification Patterns
The PB-0925ME-05Q is an externally driven AC magnetic buzzer. Its rated drive is 5 Vp-p, with a 4–7 Vp-p operating range and a 2500 Hz operating frequency. A suitable drive circuit allows audible notifications to be coordinated with equipment states and control sequences.
Vp-p describes the peak-to-peak voltage across the buzzer. The actual waveform should be measured at the device terminals, with the drive circuit implemented according to manufacturer guidance. Timing the sound-on and sound-off periods allows different notification patterns without assuming that the rated sound pressure applies at every drive frequency.
Electrical Parameters for Driver and Power-Budget Planning
The buzzer has a coil resistance of 32 ± 3 Ω and a maximum current consumption of 80 mA under rated drive conditions. These parameters provide a basis for assessing the driver load and the equipment's power budget.
Notification duration and repetition rate can be planned around the application workflow. Measuring current during sound output and across the complete operating cycle allows engineers to evaluate acoustic performance, driver capability, and average consumption together.
Operating Temperature for Equipment-Level Evaluation
The -20°C to +70°C operating range allows the PB-0925ME-05Q to be evaluated for industrial control boards and equipment notification circuits. Component placement and the expected environment should be included in the product's thermal and environmental assessment.
Before production release, test sound output and current consumption across the required temperature conditions using the final enclosure, power circuit, and notification sequence.
Specified Soldering Conditions Support Process Planning
The specified wave-soldering condition is 250 ± 5°C for no more than 5 seconds. The manual-soldering condition is 350 ± 20°C for no more than 5 seconds. Temperature and exposure time should be controlled together when validating the assembly process.
Other soldering methods require their own approved process conditions. Wave- or manual-soldering temperatures should not be treated as a reflow profile. After assembly, inspect the device and solder joints, then verify current consumption and acoustic performance.
From Component Selection to Complete-Product Validation
Begin by defining listening distance, notification timing, and the required sound output. Plan the driver around the 2500 Hz, 5 Vp-p rated operating point, verify the electrical load, and coordinate PCB placement with the sound outlet. After assembly, perform controlled acoustic measurements before testing the final enclosure, operating temperature, and application sequence.
By combining lightweight SMD construction with defined acoustic and electrical parameters, the HITPOINT PB-0925ME-05Q provides a buzzer option for high-density boards and industrial equipment, bringing acoustic, electrical, and mechanical planning into one development process.
