Traditional Components - Earphones/Acoustic Drivers

Earphones are available in two sizes, standard and miniature.

Their part numbers are derived as follows:

• Standard TC4500-ABC and Miniature TC 4400-ABC
  where ABC relate to the colour (A), impedance (B) and polarisation (C).
   
  • Colour (A) is either 1 =Grey, or 2 =Black.
    Impedance (B) can be coded 1 to 8.
    Polarisation (C) is either 0 =Polarised, or 1 =Non polarised.
    Polarised units have 2 different sized sockets for the cable plug.

Part number example (see below): TC 4500-120 =Grey, 60 ohm, Polarised
