PART NUMBER CMA-6542PF page 1 of 4 date 06/2008 DESCRIPTION electret condenser microphone SPECIFICATIONS directivity sensitivity S sensitivity reduction operating voltage output impedance Zout operating frequency f current consumption IDSS signal to noise ratio S/N operating temperature storage temperature dimensions weight material terminal RoHS note: omnidirectional -42 ±3 db f = 1KHz, 1Pa 0dB = 1V/Pa -3 dB f = 1KHz, 1Pa Vs = ~ V dc V dc standard , 10 V dc max. f = 1KHz, 1Pa 20 ~ 20,000 Hz mA max. Vs = V dc RL = 2.2KΩ 60 dBA f = 1KHz, 1Pa A-weighted -20 ~ +70° C -20 ~ +70° C g max. pin type hand soldering only 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 tolerances not shown ±0.3mm 2 PLCS 2 PLCS terminal 2 2 PLCS terminal 1 20050 SW 112th Ave. Tualatin, Oregon 97062 phone fax PART NUMBER CMA-6542PF MEASUREMENT CIRCUIT page 2 of 4 date 06/2008 DESCRIPTION electret condenser microphone FREQUENCY RESPONSE CURVE 20050 SW 112th Ave. Tualatin, Oregon 97062 phone fax PART NUMBER CMA-6542PF page 3 of 4 date 06/2008 DESCRIPTION electret condenser microphone MECHANICAL CHARACTERISTICS |
