- Presents a cost-effective audio capture solution with impressive performance characteristics.
About Electret Condenser Microphones The electret condenser microphone (ECM) is a type of capacitor microphone that utilizes a permanently charged material, eliminating the need for an external polarizing voltage.
It consists of a vibrating element that outputs a few millivolts peak-to-peak, often requiring an op-amp for signal amplification.
Electret microphones are recognized for their sensitivity, durability, and compact size.
They leverage changes in capacitance due to mechanical vibrations to generate voltage variations proportional to sound waves.
The KPCM-27B is RoHS compliant.
Reliability and Testing The KPCM-27B microphone undergoes comprehensive testing to ensure consistent performance:
- Temperature Test: Maintains sensitivity within 3dB after exposure at 55°C and 10°C for 1 hour.
- Temperature Cycle Test: Maintains sensitivity within +/-3dB after cycling between 10°C, 25°C, and 50°C.
- Humidity Test: Maintains sensitivity within +/-3dB after exposure at 40°C and 95% Rh for 48 hours.
- Vibration Test: Exhibits no operational effects after vibration at 12Hz to 50Hz for 1 minute full amplitude, for 1.5 hours on 3 axes.
- Drop Test: Shows no operational interference after being dropped onto a concrete floor once on each face from 1 meter height.
