UB1465

Overview

The UB1465 is an electret condenser microphone manufactured by Huizhou N Acoustics Co., Ltd. It features a unidirectional polar pattern and operates within a frequency range of 10 Hz to 10 kHz. The device requires a bias voltage between 1 V and 10 V for functionality. Its sensitivity is specified as -45 dB ±3 dB at 120 dB SPL. The component utilizes wire leads for electrical connection, distinguishing it from the solder pad variant.

Feature Summary

• Unidirectional acoustic pickup pattern
• Electret condenser transducer technology
• Wire lead termination style

Applications

• Voice recording devices
• Consumer audio equipment
• Communication modules

Procurement Notes

Verify the specific suffix designation when ordering, as the base model UB1465 indicates wire leads while variants like UB1465-2 utilize solder pads. Confirm that the supplier provides official datasheets from Huizhou N Acoustics Co., Ltd to ensure compliance with the stated sensitivity and voltage requirements. Cross-reference part numbers to avoid confusion between terminal types.

Selection Notes

Select this component for applications requiring a standard electret condenser microphone with wire lead connections. Ensure the circuit design supports the required 1 V to 10 V bias voltage range. Consider the -45 dB sensitivity level relative to the target sound pressure levels. Compare against the UB1465-2 if solder pad mounting is preferred instead of wire leads.

Part Context

This microphone belongs to the product line of Huizhou N Acoustics Co., Ltd, a provider of acoustic components. The UB1465 is distinct from other models in the series, such as the UB1465-2, primarily due to its termination method. It serves as a fundamental audio input sensor for various electronic devices requiring reliable voice capture capabilities.

Replacement Considerations

The UB1465-2 is a related variant from the same manufacturer but uses solder pads instead of wire leads. Direct substitution requires verifying mechanical mounting compatibility and PCB layout differences. No other cross-manufacturer substitutes are confirmed in public documentation.
