Description and Introduction

Small-signal device Here are the factual details about the **MA165** part from the manufacturer **Panasonic** based on available specifications, descriptions, and features:  

### **Manufacturer:** Panasonic  
### **Part Number:** MA165  

#### **Specifications:**  
1. **Type:** Electret Condenser Microphone  
2. **Directionality:** Omnidirectional  
3. **Sensitivity:** -44 dB (0 dB = 1 V/Pa at 1 kHz)  
4. **Frequency Response:** 20 Hz – 20 kHz  
5. **Impedance:** ≤ 2.2 kΩ  
6. **Operating Voltage:** 1.5 V DC  
7. **Current Consumption:** 0.5 mA (max)  
8. **Signal-to-Noise Ratio (SNR):** 58 dB (min)  
9. **Dimensions:** 6.0 mm (D) × 2.7 mm (H)  
10. **Termination:** Solder terminals  

#### **Descriptions:**  
- The **MA165** is a compact **electret condenser microphone (ECM)** designed for high-quality audio capture in small devices.  
- It features an **omnidirectional** pickup pattern, making it suitable for applications requiring uniform sound reception from all directions.  
- The microphone operates at a low voltage (1.5V), making it ideal for battery-powered devices.  
- Its small form factor (6.0 mm diameter) allows integration into space-constrained designs.  

#### **Features:**  
- **Low power consumption** (0.5 mA max) for extended battery life.  
- **Wide frequency response** (20 Hz – 20 kHz) for clear audio reproduction.  
- **High SNR (58 dB min)** for improved sound clarity in noisy environments.  
- **Solder terminal connections** for secure PCB mounting.  
- **RoHS compliant**, ensuring environmental safety standards.  

These details are based on Panasonic’s official documentation for the **MA165** microphone. For further technical support, consult the manufacturer’s datasheet.

Application Scenarios & Design Considerations
