TOM-1537L-HD-LW100-B-R

Overview

The TOM-1537L-HD-LW100-B-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 2.2 kOhms impedance and operates on a supply voltage range of 2 VDC to 10 VDC. The device delivers a sensitivity of -37 dB, with a signal-to-noise ratio of 68 dB and an acoustic overload point of 110 dB. Its frequency response extends up to 16 kHz, covering the standard audio band from 20 Hz to 20 kHz. The component utilizes wire lead termination for circuit integration.

Feature Summary

• Omnidirectional sound pickup pattern for uniform acoustic reception
• Electret condenser transducer technology for analog output
• Wire lead termination style for flexible board mounting

Applications

• General purpose voice recording devices
• Consumer audio equipment requiring wide-angle sound capture
• Communication systems utilizing standard analog microphone interfaces

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct lead length and termination style. Confirm that the operating voltage requirements align with your system design, as the device supports a range between 2 VDC and 10 VDC. Cross-reference the impedance value of 2.2 kOhms with your preamplifier input specifications to ensure proper signal matching and performance.

Selection Notes

Select this component when an omnidirectional response is required for capturing ambient or voice signals from multiple directions. The wide supply voltage tolerance allows compatibility with various low-voltage digital and analog circuits. Ensure the application environment does not exceed the specified acoustic overload point if high sound pressure levels are present.

Part Context

This model belongs to the TOM series of microphones from PUI Audio, designed for general audio applications. It represents a standard electret condenser solution with wire leads, distinguishing it from surface-mount variants in the same family. The HD designation typically indicates specific housing or performance characteristics within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include other omnidirectional electret microphones with similar 2.2 kOhms impedance and wire lead termination. Verify that replacement parts match the -37 dB sensitivity and 2-10 VDC operating range to maintain circuit functionality without redesigning bias networks.
