TOM-1545L-LW100-R

Overview

The TOM-1545L-LW100-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It operates within a frequency range of 100 Hz to 10 kHz and requires a DC supply voltage between 2 V and 10 V. The device features a sensitivity of -45 dB ±3 dB and an impedance of 2.2 kOhms. It utilizes wire lead termination for circuit integration.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Electret condenser transducer technology
• Wire lead termination style

Applications

• General purpose audio sensing
• Voice recognition systems
• Consumer electronic devices

Procurement Notes

Verify the specific suffix LW100-R indicates wire leads rather than SMD pads, as variations exist in the TOM series. Confirm the operating voltage range aligns with the target circuit design before procurement. Ensure compatibility with the required frequency response specifications for the intended application environment.

Selection Notes

Select this component when wire lead integration is preferred over surface mount assembly. The 2.2 kOhm impedance matches standard preamplifier inputs. Consider the 100 Hz lower frequency cutoff if low-frequency noise rejection is not required.

Part Context

This model belongs to the TOM series of microphones from PUI Audio. It shares similar electrical characteristics with other variants like the TOM-1545L-R but differs in termination method. The series is designed for compact audio applications requiring reliable omnidirectional sound capture.

Replacement Considerations

TOM-1545L-R offers identical electrical performance but uses solder pads instead of wire leads. Verify mechanical mounting constraints before substituting.
