Mundorf H71 ferrite core coil, 33mH ±3%, 1.93ohm, 0.71mm OFC-copper wire, Ø40xH37mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Mundorf P71 ferrite pipe core coil, 2.7mH ±3%, 1.01ohm, 0.71mm OFC-copper wire, Ø40xH23mm

Mundorf's P series is halfway between the L and H series, with a ferrite core (or aronit for larger models) to find a compromise between low internal resistance, small footprint and price. Ideal in car-audio or sound system.

Pipe core coil Mundorf H100, 2mH ±3%, 0.19ohm, Ø25xL35mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Mundorf H125 ferrite core coil, 2.7mH ±3%, 0.19ohm, 1.25mm OFC-copper wire, Ø40xH37mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Mundorf BS180 feron core coil, 6.8mH ±3%, 0.19ohm, 1.8mm wire OFC-copper 99.99% with backed varnish wire, feron core (iCore), 130x39xH39mm

Mundorf's BS series uses a solid 99.99% OFC copper round conductor stabilized by varnish, wrapped around a rod-shaped iron-silicon alloy core. Each end of the stick is fitted with a hole for attachment.

Mundorf L71 air core coil, 1.8mH ±2%, 1.22ohm, 0.71mm OFC-copper wire, Ø40xH20mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

Mundorf BL140 air core coil, 0.1mH ±2%, 0.07ohm, 1.40mm OFC-copper wire, Ø40xH20mm, with backed varnish wire

The BL series from Mundorf uses the same coils as the L series but with the addition of a stabilization varnish considerably reducing electromagnetically induced vibrations. If your passive filter concerns a high-end speaker, the choice of a BL coil instead of an L coil is a relevant choice because it directly impacts the listening quality.

Pipe core coil Mundorf H140, 2mH ±3%, 0.13ohm, Ø37xL40mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.
