TOM-1045S-C33-R

Overview

The TOM-1045S-C33-R is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a circular shape and solderless bullseye termination for surface mounting. The device operates within a voltage range of 2 V to 10 V with a supply current of 500 µA. Key electrical specifications include a sensitivity of -45dB ±3dB and an impedance of 2.2 kOhms. The signal-to-noise ratio is rated at 60dB. The maximum height of the component is 0.051 inches (1.30 mm), making it suitable for compact electronic assemblies requiring analog audio input.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Solderless bullseye termination design facilitates direct surface mount integration
• Low power consumption profile suitable for battery-operated portable devices

Applications

• Consumer electronics audio input modules
• Medical equipment voice control interfaces
• Industrial control panel microphones

Procurement Notes

Verify the specific suffix 'R' indicates the required tape-and-reel packaging configuration if automated assembly is planned. Confirm that the solderless bullseye termination matches the PCB pad layout. Ensure the operating voltage range aligns with the target circuit's biasing requirements before finalizing procurement orders.

Selection Notes

Select this component when an omnidirectional response is necessary for ambient sound capture in space-constrained designs. The low profile and specific termination style are critical for compatibility with existing surface-mount manufacturing processes. Evaluate the -45dB sensitivity against the pre-amplifier input requirements to ensure adequate signal levels without excessive noise.

Part Context

This part belongs to the TOM series of electret condenser microphones produced by PUI Audio, Inc., a manufacturer specializing in audio components for industrial and consumer markets. The series offers various sensitivity and termination options to accommodate different design constraints.

Replacement Considerations

Cross-reference with other models in the PUI Audio TOM series for alternative sensitivities or termination styles. Verify pinout and dimensional compatibility before substituting with generic equivalents.
