HBO0303C-60

Microphones Overview

The HBO0303C-60 is a back electret condenser microphone manufactured by BeStar Technologies, Inc. It features an omnidirectional polar pattern and analog output type. The component operates within a voltage range of 1 V to 10 V, with a rated voltage of 3 V. Key electrical specifications include a sensitivity of -40 dB ±3 dB (referenced at 1 V/Pa) and an impedance of 2.2 kOhms. The supply current is specified as 500 µA. The frequency response covers the range from 20 Hz to 10 kHz. The physical dimensions are characterized by a diameter of 0.118 inches.

Microphones Feature Summary

• Back electret condenser construction for stable acoustic performance
• Omnidirectional pickup pattern for uniform sound capture from all directions
• Analog output signal generation suitable for standard audio processing circuits

Microphones Applications

• General purpose voice recording devices
• Consumer electronic audio input modules
• Telecommunication equipment microphones

Microphones Procurement Notes

Verify the specific datasheet version from BeStar Technologies to confirm mechanical tolerances and soldering thermal profiles. Ensure compatibility with existing PCB footprint designs regarding the 3mm package size. Confirm that the required operating voltage aligns with the 1 V to 10 V specification range for your target application circuit.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general audio capture rather than directional noise rejection. The fixed -40 dB sensitivity suits applications where moderate gain amplification is available in the subsequent signal chain. Consider the 500 µA supply current requirement for battery-powered designs to ensure adequate power budget allocation.

Microphones Part Context

This part belongs to the SoniCrest brand acoustic components line produced by BeStar Technologies, Inc. The company specializes in manufacturing acoustic, haptic, and sensor components. The HBO series represents their standard electret condenser microphone offerings designed for integration into various consumer and industrial audio systems.

Microphones Replacement Considerations

The HBO0302C-58/1248 is a related product from the same manufacturer. Verify if its -38 dB sensitivity meets the system requirements, as it differs from the -40 dB specification of the HBO0303C-60. Cross-reference mechanical dimensions to ensure board compatibility before substitution.
