TOM-1545S-C33-R

Overview

The TOM-1545S-C33-R is an analog electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern with a sensitivity of -44 dB and an impedance of 2.2 kOhms. The device operates on a supply voltage ranging from 2 V to 10 V with a current consumption of 500 uA. Its frequency response spans 20 Hz to 20 kHz. The physical dimensions are 4 mm in diameter and 6 mm in length, utilizing solder pin termination for PCB mounting.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Electret condenser transducer technology
• Low power consumption operation
• Standard solder pin termination

Applications

• Consumer audio recording devices
• Voice recognition systems
• General purpose sound detection circuits

Procurement Notes

Verify the specific suffix 'R' indicates RoHS compliance when sourcing. Confirm the manufacturer is PUI Audio, Inc., as distributors may list similar models with different lead content statuses. Ensure the operating voltage range of 2 V to 10 V matches the target circuit design before procurement.

Selection Notes

Select this component for applications requiring a compact, low-power omnidirectional microphone. The 2.2 kOhm impedance and -44 dB sensitivity are suitable for standard pre-amplifier interfaces. Consider the 4 mm diameter constraint for tight enclosure designs. Verify that the solder pin termination method aligns with the assembly process.

Part Context

This part belongs to the TOM series of microphones from PUI Audio, Inc. It is distinct from the non-compliant TOM-1545S-C33 variant due to its RoHS status. The series provides standardized form factors for integration into portable electronic devices requiring reliable analog audio input.

Replacement Considerations

The TOM-1545S-C33 is a direct mechanical substitute but lacks RoHS compliance. Other models in the TOM series may share dimensions but require verification of electrical parameters such as sensitivity and impedance before substitution.
