Sensitivity: -613dB (0dB=1V/1 bar 1 KHz) Generally, semiconductors are easily weakened by over- Output impedance: 1K heating, and over-charge of voltage. Frequency: 50Hz~16KHz Special caution is needed for proper soldering as follows: Standard voltage: 4.5V 500A 1. Use 30W (or under) soldering iron and maintain Current drain: max. 230-260C in operation. S/N ratio: 60dB or more 2. Soldering should be accomplished within two seconds at Maximum input sound pressure: 104dB SPL each terminal so as not to be overheated. Mechanical Specifications: 3. Do not make a cavity at the surface of lead on the pattern Storage temperature: -20C to 60C plate. (A cavity may change the characteristics of the mic.)
