The higher quantity options are cheaper per item. The wire is reasonably thick 7 X 0.2 type and is relatively easy to handle during installation without breaking it. These require a low noise power supply of between 1.5 and 10V fed via a resistor of approximately 1K Ohms connected to the red wire. The standard voltage for this type is 4.5V. A D.C. blocking capacitor of something like 10uF is then typically used to feed the signal into the microphone pre-amplifier. Some tape recorder microphone inputs may have this power supply and capacitor internally, in which case they will generally state that on the machine. The sensitivity is -64dB +\/-3dB at an operating voltage of 4.5V. The current drain is 0.5mA maximum, S\/N ratio is 40dB or better. The output impedance tends to be dominated by the bias resistor, so in the typical case it will always be less than 1K. A data sheet is shown in the secondary pictures. The diameter is 10mm and the total height including the solder terminals and wires is 8mm.\u003c\/p\u003e","brand":"HJW Electronics","offers":[{"title":"1 Mic","offer_id":58833396138368,"sku":null,"price":2.8,"currency_code":"GBP","in_stock":true},{"title":"2 Mics","offer_id":58833396171136,"sku":null,"price":5.2,"currency_code":"GBP","in_stock":true},{"title":"3 Mics","offer_id":58833396203904,"sku":null,"price":7.4,"currency_code":"GBP","in_stock":true},{"title":"4 Mics","offer_id":58833396236672,"sku":null,"price":9.3,"currency_code":"GBP","in_stock":true},{"title":"5 Mics","offer_id":58833396269440,"sku":null,"price":10.9,"currency_code":"GBP","in_stock":true},{"title":"10 Mics","offer_id":58833396302208,"sku":null,"price":19.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/j60_wires_top_s.jpg?v=1788287747","url":"https:\/\/shop.usefulcomponents.com\/products\/electret-condenser-microphone-with-pre-soldered-wires","provider":"HJW Electronics","version":"1.0","type":"link"}
