Mundorf L50 air core coil, 3.3mH ±2%, 3.13ohm, 0.50mm OFC-copper wire, Ø30xH20mm

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 L125 air core coil, 1.5mH ±2%, 0.47ohm, 1.25mm OFC-copper wire, Ø58xH28mm

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 CFC16 air copper foil coil, 1.8mH ±2%, 0.5ohm, 17x0.07mm OFC-copper wire, Ø68xH24mm, with backed varnish wire

La bobine série CFC est une self à air constituée d’un enroulement de feuille de cuivre OFC 99.99% séparé par une feuille d’isolation polypropylène de 0.02 mm. La partie centrale est percée pour la fixation.

Mundorf BL71 air core coil, 3.3mH ±2%, 1.76ohm, 0.71mm 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.

Mundorf L100 air core coil, 0.12mH ±2%, 0.15ohm, 1.00mm OFC-copper wire, Ø30xH20mm

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.

Air core coil Mundorf BL71, 0.082mH ±2%, 0.2ohm, Ø10xL25mm, with backed varnish

Mundorf BL140 air core coil, 4.7mH ±2%, 0.77ohm, 1.40mm OFC-copper wire, Ø70xH59mm, 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.

iCore feron coil Mundorf BS140, 3.9mH ±3%, 0.19ohm, 96x31xH31mm

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.
