Overview
The AT-1620-TWT-R is an electromagnetic transducer manufactured by PUI Audio. It features a round shape with a 16 mm diameter and 14 mm depth, designed for PCB mount installation via solder pins. The device operates at a resonant frequency of 2.048 kHz with a sound pressure level of 90 dBA. Electrical specifications include a 50 Ohm impedance, 6 V voltage rating, and 40 mA current rating. It functions within a temperature range of -20°C to +70°C.
Feature Summary
- Electromagnetic transduction mechanism for audio output
- Round form factor optimized for compact board mounting
- Solder pin termination for direct PCB integration
Applications
- Electronic device status indicators
- Audible alert systems in consumer electronics
- General purpose audio signaling components
Procurement Notes
Verify the specific datasheet version for the AT-1620-TWT-R to confirm RoHS compliance details and exact physical tolerances. Ensure the driving circuit matches the 50 Ohm impedance and 6 V rating to prevent damage. Confirm that the operating environment stays within the specified -20°C to +70°C range for reliable performance.
Selection Notes
Select this component when a compact electromagnetic solution is required for audible signaling at approximately 2 kHz. The 16 mm diameter fits standard small-footprint designs. Consider the 90 dBA output against enclosure attenuation requirements. Verify that the PCB layout accommodates the solder pin spacing and height constraints.
Part Context
This part belongs to the AT series of transducers from PUI Audio, which focuses on electromagnetic audio components. The series provides various frequencies and sizes for different acoustic needs. The AT-1620-TWT-R specifically targets applications requiring a balance between size and sound pressure at mid-range frequencies.
Replacement Considerations
Consult official PUI Audio documentation for verified substitute part numbers. Do not assume cross-compatibility with other series without checking electrical and mechanical parameters.
