No interference in operation. PCB wire pull strength The force of 4.9 N is applied for 30 sec. to double lead wire. No damage or cutting off. vibration test The microphone should be measured after a vibration amplitude of 1.5 mm with 10 ~ 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. drop test The microphone without packaging is subjected to 3 drops on each axis from the height of 1 m onto a 10 mm thick wooden board. The sensitivity should be within ±3dB compared with the initial measurement. ENVIRONMENT TEST item test condition high temperature test After being placed in a chamber at +70°C for 72 hours. evaluation standard low temperature 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% RH for 240 hours. temperature cycle test The part will be subjected to 10 cycles. One cycle will consist of: +70к +25к +25к -20к 1hr 0.5hr 1hr 0.5hr 1hr 0.5hr The microphone will be measured after being placed at +25°C for 6 hours. The value of the oscillation frequency should be ±10% compared to the initial measurements. The SPL should be within ±3dB compared to the initial measurements. 1hr 5.5 hrs TEST CONDITIONS standard test conditions a) Temperature: +5 ~ +35°C b) Humidity: 45 ~ 85% c) Pressure: 860 ~ 1060 mbar judgement test conditions a) Temperature: +25 ±2°C b) Humidity: 60 ~ 70% c) Pressure: 860 ~ 1060 mbar 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 www.cui.com For more information, please visit the product page. date 06/2012 page 4 of 4 DESCRIPTION: ELECTRET CONDENSER MICROPHONE PART NUMBER: CMI-4537-SN69 PACKAGING ʳ˥̂˛˦ʳ˖̂̀̃˿˼˴́̇ʳʳ Small box Middle box Carton size 100mm*100mm*10mm 205mm*105mm*50mm 420mm*230mm*255mm 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 100PCS/ Small box 1000PCS/ Middle box 20000PCS/ Carton fax 503.612.2383 www.cui.com
