DESCRIPTION: electret condenser microphone 1 of 4 PART NUMBER: CMC-5044TF-A SPECIFICATIONS directivity omnidirectional sensitivity (S) -44 ±3 db f = 1KHz, 1Pa 0dB = 1V/Pa sensitivity reduction (ΔS-Vs) -3 dB f = 1KHz, 1Pa Vs = 2 ~ 1.5 V dc operating voltage 2 V dc (standard), 10 V dc (max.) output impedance (Zout) 2.2 K Ω f = 1KHz, 1Pa operating frequency (f) 100 ~ 20,000 Hz current consumption (IDSS) 0.5 mA max. Vs = 2 V dc RL = 2.2K Ω signal to noise ratio (S/N) 60 dBA f = 1KHz, 1Pa A-weighted operating temperature -20 ~ +70° C storage temperature -20 ~ +70° C dimensions ø6 x 5 mm weight 0.30 g max. material Al terminal terminal type (hand soldering only) RoHS yes note: We use the “Pascal (Pa)” indication of sensitivity as per the recomendation of I.E.C. (International Electrotechnical Commission). The sensitivity of “Pa” will increase 20dB compared to the “ubar” indication. Example: -60dB (0dB = 1V/ubar) = -40dB (1V/Pa) APPEARANCE DRAWING terminal 2 terminal 1 0.25.0 6.0 0.2 tolerances not shown: ±0.3mm

DESCRIPTION: electret condenser microphone 3 of 4 PART NUMBER: CMC-5044TF-A ENVIRONMENT TEST item test condition high temp. test After being placed in a chamber at +70°C for 72 hours. low temp. test After being placed in a chamber at -20°C for 72 hours. humidity test After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. temp. cycle test The part shall be subjected to 10 cycles. One cycle will consist of: evaluation standard The part will be measured after being placed at +25°C for 6 hours. After any tests, the sensitivity should be within ±3dB compared to the initial measurement. MECHANICAL CHARACTERISTICS item test condition soldering heat resistance Soldering iron of 270 ±5°C should be placed on the terminal for 2 ±0.5 seconds. PCB wire pull strength The pull force will be applied to double lead wire: Horizontal 4.9N (0.5kg) for 30 seconds vibration The part will be measured after applying a vibration amplitude of 1.5 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. drop test The part will be dropped from a height of 1 m onto a 20 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops. evaluation standard No interference in operation. No damage or cutting off. After any tests, the sensitivity should be within ±3dB compared to the initial measurement. TEST CONDITIONS standard test condition a) temperature: +5 ~ +35°C b) humidity: 45 - 85% c) pressure: 860-1060 mbar judgement test condition a) temperature: +25 ±2°C b) humidity: 60 - 70% c) pressure: 860-1060 mbar
