产品特点 FEATURES

1 Brand: PUIAUDIO, Model: SMT-0825-S-4-R, a surface-mount electro-mechanical transducer.

2 Electrical parameters: Rated voltage of 3.6Vp-p, operating voltage range of 2.5-4.5Vp-p; rated current (max) of 15±3mA; coil resistance of 90 ohms.

3 Acoustic performance: Minimum sound pressure level (SPL) of 85dBA at 10cm; resonant frequency of 2500±500Hz.

4 Environmental adaptability: Operating temperature range of -30 to +70°C; storage temperature range of -40 to +85°C.

5 Material and construction: Housing made of LCP (Liquid Crystal Polymer); terminal material is Sn-plated phosphor bronze; weight of 0.4 grams.

6 Compliance and soldering: RoHS 2011/65/EU compliant; suitable for reflow soldering with max temperature of 260°C for ≤10 seconds.

7 Mechanical design: SMT package with clear polarity marking (PAD (+) and (-)) on the housing; dimensions in millimeters as per specification, suitable for automated assembly processes.

使用场景 APPLICATIONS

1 Consumer electronics: Suitable for integration into smartphones, tablets, smartwatches, and fitness trackers to provide audio notifications (like incoming calls, messages, or app alerts).

2 IoT and smart home devices: Used in smart doorbells, smoke detectors, temperature/humidity monitors, and smart plugs to emit warning sounds or status prompts.

3 Industrial equipment: Applied in small control panels, portable measurement instruments, and embedded systems for audio feedback on operational status or error warnings.

4 Automotive interior components: Compatible with in-car infotainment systems, dashboard alert modules, and parking sensors (where operating temperature requirements are met) to deliver audio cues.

5 Medical devices: Ideal for portable diagnostic tools, patient monitors, and wearable health devices that need lightweight, compact audio transducers for notifications.

注意事项 PRECAUTIONS

1 Voltage usage: Do not operate the transducer outside the specified voltage range (2.5-4.5Vp-p) to prevent coil damage or reduced performance.

2 Soldering precautions: Follow reflow soldering guidelines strictly—avoid exceeding 260°C for more than 10 seconds; do not use wave soldering as it may damage the SMT package.

3 Polarity connection: Ensure correct polarity (PAD (+) and (-)) during installation to ensure proper sound emission.

4 Storage and handling: Store the transducer in a dry environment within the storage temperature range (-40 to +85°C); avoid applying force to the sound emission hole or housing to prevent deformation.

5 Compliance: Adhere to RoHS regulations when using the product in regions where such standards are mandatory.
