Mundorf BS180 feron core coil, 1mH ±3%, 0.06ohm, 1.8mm wire OFC-copper 99.99% with backed varnish wire, feron core (iCore), 106x33xH33mm

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.

Air core coil Mundorf BL100, 2mH ±2%, 0.74ohm, Ø22xL58mm, with backed varnish

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.

Air foil coil Mundorf CFC16, 2mH ±2%, 0.55ohm, Ø24xL70mm

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.

iCore feron coil Mundorf BS140, 2.2mH ±3%, 0.15ohm, 84x28xH28mm
