BCM4013OLFC-42-JST-ZHR-2

Overview

The BCM4013OLFC-42-JST-ZHR-2 is an active electret condenser microphone manufactured by BeStar Technologies, Inc. It features an omnidirectional polar pattern and provides an analog output signal. The device operates within a frequency range of 50 Hz to 16 kHz and supports a voltage range of 1 V to 10 V. Key electrical specifications include a sensitivity of -42 dB and an impedance of 2200 Ohms. The physical dimensions are characterized by a diameter of 0.157 inches (approximately 4 mm). This component is designed for general audio capture applications requiring reliable performance across the specified acoustic bandwidth.

Feature Summary

• Omnidirectional sound pickup capability for uniform acoustic reception
• Electret condenser transducer technology for analog signal output
• Wide operating voltage tolerance supporting flexible circuit integration

Applications

• General purpose audio recording devices
• Voice recognition systems
• Consumer electronic audio input modules

Procurement Notes

Verify the specific suffix JST-ZHR-2 against official BeStar documentation to confirm lead wire termination details. Ensure the procurement channel sources genuine components from authorized distributors to guarantee electrical parameter consistency. Cross-reference the datasheet revision date with manufacturing lot codes to validate product authenticity and compliance with current production standards.

Selection Notes

Select this component when an omnidirectional response is required for ambient sound capture. The -42 dB sensitivity and 2200 Ohm impedance must align with the preamplifier input requirements of the target design. Confirm that the 50 Hz to 16 kHz frequency range adequately covers the intended voice or audio spectrum without necessitating additional equalization stages in the signal chain.

Part Context

This model belongs to the BCM4013 series of electret condenser microphones produced by BeStar Technologies. The series includes variants with different termination methods, such as solder pads or wire leads. The BCM4013OLFC-42-JST-ZHR-2 specifically denotes the version equipped with round wire leads, distinguishing it from surface-mount alternatives like the BCM4013OSBC-42 within the same functional family.

Replacement Considerations

The BCM4013OSBC-42 serves as a related variant within the same product line, offering identical electrical characteristics but utilizing a solder pad configuration instead of wire leads. Verify mechanical footprint compatibility before substitution. No other direct cross-model replacements are confirmed in available public documentation.
