TM141044

Overview

The TM141044 is an omnidirectional electret condenser microphone manufactured by Top Shelf Acoustics, LLC. It operates within a frequency range of 50 Hz to 10 kHz and requires a supply voltage between 1 V and 10 V. The device features a sensitivity of -40 dB ±3 dB and offers a signal-to-noise ratio of 60 dB (A-weighted). Electrical specifications include a maximum impedance of 1.5 kΩ and a maximum input sound pressure level of 110 dB at THD ≤3%. The component utilizes solder pads for connection.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Electret condenser transducer technology
• Solder pad termination interface

Applications

• General purpose analog audio capture
• Voice recognition systems
• Consumer electronic audio interfaces

Procurement Notes

Verify the manufacturer part number TM141044 against official Top Shelf Acoustics documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with the required 1 V to 10 V bias voltage range. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm solder pad orientation and spacing during mechanical integration.

Selection Notes

Select this component when an omnidirectional response is required for uniform sound capture from all directions. The fixed sensitivity of -40 dB suits applications where moderate gain stages are available. Verify that the operating environment does not exceed the 110 dB maximum input sound pressure level to prevent distortion. Ensure the circuit design supports the specified 1.5 kΩ maximum impedance.

Part Context

This model belongs to the Top Shelf Acoustics electret condenser microphone series. It shares the omnidirectional design philosophy with other models in the lineup but differs in specific electrical characteristics and package details compared to cardioid variants like the TM141050. The series focuses on standard analog microphone implementations for general audio applications.

Replacement Considerations

Direct substitutes require matching omnidirectional polar patterns and similar sensitivity levels. Verify pinout compatibility for solder pad connections. Cross-reference with other Top Shelf Acoustics omnidirectional models if exact specifications are unavailable, ensuring voltage requirements remain within the 1 V to 10 V range.
