Mundorf is regarded as specialist in high-end components.
We have, therefore, listed the most interesting ones below. All listed coils
are made of copper lacquer wire with a purity of > 99.995%. The coil body
is made of glass fibre reinforced polyamide. The wire ends are tinned and
labelled. Inductance is measured at 25 degrees Celsius; tolerance is +/- 3%.
L denotes inductance, R the DC resistance, D the diameter, Le the length,
W the width, H the height.
Air coils (i.e. coils without a ferro-magnetic core) are absolutely distortion-free,
which on the face of it makes them ideal for all audio applications. The trouble is,
their electrical resistance increases with their inductance. There are two solutions
to this problem: One can either use very thick windings (this is why our standard range
includes windings with wire up to 3mm in diameter) or coils with cores. Lower cost and
smaller size are also common reasons for choosing cored coils.
The power values Pmax in the following tables were determined at 20 degrees Celsius ambient temperature and free convection. They are just a guideline and - since we are not the manufacturers - cannot be guaranteed by us.
